In OHF on AvP, the setup for Frontier is a mixed species team match of 2 teams. The ability of this allows each team to have their own plans and tactics without revealing them to the other team. At least 8 players are needed to play, while 16 is the maximum. This mode truely allows players to show loyalty or skill, 2 of the Five Methods to rank up (see "Ranks"). One team is the Royals, while the other team is the Opposers. The Royals team is often alien in species and has the current host subleader, while the Opposers may often vary in species and members. The members who join the Royals are showing loyalty to the Matriarch, while the Opposers are players attempting to show skill. The rewards of this game are very generous, for the winning team all ranks up once. There is no second-place reward.
Dethrond is one of the 2 similar modes of Operation: Hive Frontier, created by BamaMercenary. The Royals team of aliens is up against an Opposer team of other aliens, just like the K-series aliens from Aliens vs. Predator: Extinction. The aliens in this mode are "no longer loyal to their queen" and are "attempting to overthrow her." The team leader of the Opposers is a predator, the only one in this match (no smartdiscs or plasma caster permitted). This predator is leading a rebellion against the Matriarch, in this case. The Opposers are showing their skill against the Matriarch, who is the leader of the Royals team. Both teams need to defend their group leader. To begin the match, teams should try to start on opposite sides of the map (this should be planned ahead). The 2 teams must start in one general area, and after 1 minute after the match's beginning (time to gather to one side of the map and plan), the battle begins. The teams send out all "offenders" to battle, while "defenders" defend their group leader. The whole idea of this mode is to kill the other groups' leader. The group leaders may fight, but it is not advised for their well-being and how quick the match could end. The group leaders should go to more reclusive areas of the map. Once the other team's leader has been killed 3 times, the current winning team's leader must signal the end of the match by 3 hisses or 3 plasma shots in the center of the map. If both sides' leaders die 3 times before the other can signal, a stalemate occurs where the two leaders must face off where the signal would be given. If the Opposers win the aliens will have "usurped the corrupt queen and taken over as the new Hive leaders." The Royal's winning means the "corrupt queen keeps her position as another rebellion is stopped under her reign." To decide the winner, a minitournament must be played. Another battle must begin and will be done the same way. There can be 3 battles at most, the best 2-out-of-3 is the winning team. The winning team ranks up once for each player, and each member also recieves a bonus ranking up slightly from loyalty or skill, depending on which team wins.
Assault mode is the second mode of OHF, to which the Opposers are marines. This mode was created by teddytom. Once again, the Opposers' team leader is a single predator, who cannot use smartdiscs, plasma casters, and now proximity mines. The Royal's team leader is once again the Matriarch. In fact, this setup is pretty much the same as Dethroned mode, but is played with marines instead. Players have a minute to gather and plan at the beginning, then the match begins. From here, members either attempt going out and killing the other team or stay back and defend the team leader. The objective once again is to kill the other group leader 3 times. Once that is done, the winning team has won one battle. No signaling needs to occur. The same setup is used, as another battle begins and it is a best 2-out-of-3 battle wins to win the minitournament and for the whole team to win first place. From here, the Opposers winning means they "have killed all the xenomorphs and have saved the universe" (not really). If the Royals win, then they "have crushed all the marines and any hope to defeat the all-powerful Hive" (not really). The winning team ranks up once and recieves a bonus to whatever Method of ranking up they did, loyalty or skill.
Created by Matriarch italian-stal, Duel mode is different to the original modes of Operation: Hive Frontier. Here, the Opposers team can be all 3 species, but the team must choose one for all the players to play as (i.e. if the team chooses marines, the whole team must be marines, including the group leader). The Royals, once again, play as aliens and have the Matriarch as their clan leader. Each battle bgins just as it does in Dethroned and Assault modes: each team has the first minute of each battle to gather and plan on one side of the map. In this mode, however, all players are offensive, including each group leader. Once the battle begins, each player kills each other. Once a member of each team dies, they are out for the battle. The only ones with infinite lives for this section of the battle are the group leaders. Other members must hide or go into some spot where they will not interfere. Once all the members of one team's reinforcements are dead, then the group leaders will face off at the Diamond location in the Big Room. The team that had surviving players from the first part will help their leader during the faceoff. From here, all members may come and watch, but not interfere if they were dead players. The group leaders must kill each other 3 times. The first team to kill the other group's leader during this phase wins that battle. The group leader with extra players will indeed have a fair advantage over the single opponent. Just like before, this must be done twice, or 3 times if there is a tie, for it is best 2-out-of-3 battle wins. The first team to wins 2 battles wins the minitournament and first place, where they will rank up once each and recieve a bonus ranking up a bit for either loyalty or skill, whichever they used.
Another odd mode out is Blitzkrieg mode of OHF. Member pupgod768 created this mode after a game in his own clan, and this mode may be the quickest of any in Hive Frontier. The word blitzkrieg translates to "lighting battle tactic," an actual historic war tactic, hence the game's speed. This mode will be done fast and easily, but like the other OHF modes, it is a series of 3 battles (or 2 if the same team wins twice in a row) to win the reward. To play, the Royals must be aliens, like normal. The Opposers, like Duel mode, choose their team species. Unlike Duel mode, the Opposers leader must be a different species from their team. If the team is predators, for example, the team leader must be either an alien or marine. The Royals leader is still an alien, but a praetorian skin. Now this mode is usually played in Ruins, where the map is large and open. For the first minute, like all modes, no teams attack, but they gather in their room and plan out battle tactics. Here, the Royals start in the Pillar Room, while the Opposers spawn in the Tree Room. After the first minute is up, the match begins. This mode is different from the others because one team is restricted, while the other is free to move. During a first battle, the Royals team is not allowed to leave the Pillar Room. The Opposers are supposed to come to them and murder them. Now, the purpose of the game is to completely annihilate the other team. If a member dies twice (each normal player has 2 lives), they go to the room that is not being attacked to wait out the rest of the battle. The only difference in team leaders is that they each have 5 lives, instead of one. If a leader dies, their team may continue to fight, but their most-powerful member is dead. Once an entire team is whiped out, the remaining team with at least one member left wins that battle. The winning team's leader, whether they are out or not, will hiss, shoot plasma 3 times, or shoot 3 grenades to end the battle. In a second battle, the Royals attack the Tree Room, where the Opposers are trapped. A tiebreker match has the Royals in the Pillar Room again. The first team to win 2 battles wins. If a rare Double-Kill glitch (two members die at the same time) occurs, no-one wins that battle.
However, there is a special method to play Blitzkrieg mode specifically. This is called the Protection Method, created by pythor085. In this method, the teams are already premade, with one full team being aliens (the Royals), and one full team of marines (the Opposers). The Protection method is the only exception for a team leader having to be a different species in Blitzkrieg mode. Now, the marines get to use every weapon but the smartgun and the buckshot of the shotgun. In this mode, one marine will be chosen leader and one alien of praetorian skin will be the other leader. This is the exact setup of Blitzkrieg mode, but it is in Gateway. The aliens will start in the cave part of the map (the Council Caverns). The Opposers will start in the compound area. In all rounds, however, the marines will always invade the alien territory, not viceversa like in normal Blitzkrieg. The same number of lives are used, and the first team to win 2 battles receives the same reward as normal Blitzkrieg mode.
The fifth mode of OHF is Transmutation, which was inspired by MaxDeadBear during the reign of dragonsrule4444, years after Blitzkrieg had been released under italian-stal. Unlike all previous modes of Frontier, Transmutation follows rules somewhat closer to Hive Domination in the fact that the leader of this mode changes throughout each match/battle; one person will not remain the leader of their team for the entire match. Like with Blitzkrieg and Duel modes, the Opposers may choose their species, but here so may the Royals as well. There is but one restriction: each team may only have up to one predator player per team. Predators may only use combi sticks, while marine players may use all but the scoped rifle. Before the match, as with all modes, the teams will choose their first leader in front of the opponent team, so that each side knows the opposite team's first leader when the game begins. Once the match starts, however, each team will go to their appropriate side of the map for the first 2 minutes (as opposed to the usual 1). During this time, each team will then choose 3 more people to be leaders throughout the match in a particular order (a 2nd, 3rd, and 4th leader) privately so that the other team will not know this sequence. No one person may be allowed leadership more than once per match. Once the game begins, each team will then attempt to hunt down the other team's first leader (which they know) or will attempt to defend their own first leader. Once a team's first leader dies, the second-chosen leader of that team will then come to power and must attempt to survive. This continues on for the 3rd and 4th leaders. Between each leader's death, a team must signal to the other team that a change in leadership had occurred, and that the other team has correctly eliminated the first team's leader at that time. This may be done by 3 alien hisses, 3 marine grenades, 3 plasma shots, or by text chat. Once a team's fourth leader is eliminated, the winning team's fourth leader (even if not in power at the time) must go the the center of the map and signal the battle's end. This is by 5 plasma shots, 5 alien hisses, or 4 grenades (depending on fourth leader's species). If both teams' fourth leaders are eliminated before either side can signal the end, a stalemate similar to Dethroned mode occurs and the two 4th leaders must face off. Between battles of this mode, the sequence of leaders may be changed. Once again, best 2 of 3 battles wins the game.
The Repetition method of Transmutation mode was released with the mode when it came out, and follows all of the rules of the original. However, in this mode (a) member(s) of the team may be leader more than once per battle, as in they can be selected as one or two of the four leaders during a battle's sequence. The only restriction is that each person cannot be two successive leaders in a row (ex. first and second leaders); their leaderships must be separated by at least one other leadership (ex. first and third leaders).
Kamikaze is the sixth mode of OHF, created again by MaxDeadBear. This was also the first mode released under Matriarch sdrbuck234. As with most modes of Frontier, the Royals and Opposers teams will each choose a leader before each match. In this mode, however, both team leaders must play as predators, while all remaining members must play as all aliens or marines, with the Royals playing as only aliens. Marine players may not use shotguns or smartguns. For the first two minutes of the match, each team will go to their designated half of the map, while the team leaders will each get mines. With this, the predators will fulfill not only the role of leaders in this mode, but Rechargers as well. In this way, Kamikaze mode is the Frontier version of Suicide mode of Hive-and-Seek. Once the first minute is up, the members of each team will then attempt to take out the enemy's leader or protect their own, as with typical modes of OHF. However, team leaders will have 6 lives each, and celkworm's Suicide tactic is implemented. This means that the predator leaders can place mines on one or more teammates. The objective of these Bombers is to then attempt to suicide bombing the other team's Recharger leader. If the opposing team's pred blows up from the mine blast, it is worth 3 of the leader's 6 lives, or half of their health. Any normal kills (i.e. marine or alien directed kills) on the other team's leader is only worth one life, making the Suicide tactic a much more quick and efficient, albeit difficult, method of taking out the opposing leader. Because of the Pass-by tactic that may blow up the Bomber through any close interference of opposing members, this makes the Bomber's journey to the opposing leader difficult, especially in tight maps. This makes teamwork to protect the team's leader AND clear a way for the Bomber imperative, and the allocation of members very specific, as in most cases the Bomber will need at least one teammate to help them reach the enemy predator. Once all lives of a team's pred are depleted, the winning team's leader must then finish off that losing pred with their final, seventh life. This seventh life is only available after the first six are gone, and only the team's leader may get this life using regulated weapons (only melee and mines). (*Note: during this time, the winning team will likely go all offensive to help its leader finish off the other team's. If done correctly, the losing team should go all defense and attempt to get the rest of the winning pred's 6 lives before they can finish off their own leader, thus catching that team up to the point where both teams' leaders need only get one kill on the other in a stalemate.) Once this is done, that team wins that match. As with other modes, multiple matches will be played for a best 2 out of 3.
