Betrayal is played in Instagib mode on regular Deathmatch maps. While players form temporary alliances during the match, Betrayal is still a free-for-all gametype where the winner is the player, not the team, who reaches the goal score first or has the highest score when time limit hits. The gametype's name also is its main twist: You can betray the members of your current team by killing them with the alternate firing mode of your Super Shock Rifle. After successful betrayal, the player takes the team pot and becomes a rogue for 30 seconds. The rogue's former teammates can get payback during that period. After avoiding payback or when getting fragged by a former teammate, the player becomes a freelancer again and will join the next team.
In Betrayal, the only weapon is a special version of the Super Shock Rifle which shoots two beams: red for enemies and blue for teammates.
If the killed player has a higher total score than the killer, the difference is divided by 4 and the result, limited to 9, is added to the killing score. This way, a regular kill can be worth up to 10 points and players who are far behind have a good chance to catch up again.
Players who are in a team add one point into the team pot for every opponent they kill.
If a player becomes a rogue by betraying the team, he not only gets the regular kill score, but also takes the team's pot and adds it to his score.
Rogues and freelance players don't add to any teams pot when they kill opponents.
If a rogue is killed by one of his former team mates, then the killer gets a bonus of 6 points in addition to the regular kill score.
Don't betray your team right away, it's not worth the trouble. By betraying your team, you only get the team pot as bonus. But by getting payback on a betrayer, you get a fixed bonus of 6 points.
The indicator in the upper middle of the HUD shows how trustworthy your current team mates are. For every betrayal they ever comitted in the match, they have a dagger behind their name. After betrayal this HUD indicator also tells you how long you still have to avoid the team mates you betrayed or how long you can still seek payback on the betrayer.
You can be put on a new team while you still have time to get payback on a player. If you are betrayed again, you can no longer get payback on the old betrayer, so be sure to get him quickly.
Watch out for blue shock beams, they are an indicator of someone trying to betray a team mate. If they come from one of you team mates, you may need to defend yourself by betraying first.
If you are the one trying to betray, make sure you aim carefully. If you miss, your blue beam will alert your team mate of your betrayal attempt and may provoke him to betray you instead.
"Betrayal is a new instagib game type that pits players against each other while they cooperate in temporary alliances. Only one player is the final winner, and the difference between victory and defeat often lies in knowing when to betray your teammates.
A score above opponents’ heads reflect their value if you gib them using the primary fire of your instagib rifle. Current teammates are blue, and every kill by a teammate adds one point to the team pot, which is shown at the top of your HUD. Teammates can betray each other using the alternate fire of the rifle, which shoots a blue beam. Assassinating a teammate gives the assassin both the score over that player’s head, plus all the points accrued in the team pot.
However, the assassin becomes a Rogue for 30 seconds, during which he is not on any team, and his former teammates can garner a score bonus for achieving retribution by killing him. The score above a Rogue’s head is red for his former teammates. Once the rogue timer has counted down, the rogue will automatically join a new team when teammates are available.
Daggers beside each player’s name shows the number of times that player has betrayed his teammates. Watch your back around teammates; you’ll often see players pause and check each other out as they enter a room together.
Sometimes, players may try to goad a teammate into killing them by shooting blue beams by their ear when the team pot is small, hoping to later cash in on the retribution bonus. As the players near victory, they’ll often try to time a final betrayal to send them over the top."
"The second Titan Bonus Pack game mode is Betrayal, a somewhat confusing Deathmatch hybrid played with modified Insta-Gib rifles. At map load each player is placed into a three-man, blue-coloured 'team.' With primary fire the objective is to kill everyone else, with each kill increasing your personal score. If the enemy player has numerous kills to his name your score further increases. Each of these kills, either by you or your two teammates, increases a shared 'pot.' Once it is at a sufficiently high level, or even if it’s not, you can alt-fire kill your teammates to grab the entire pot for yourself, again boosting your score by a significant amount. Once this 'betrayal' has been initiated, a thirty-second countdown timer begins, during which time you are team-less. In this brief window, the players you betrayed can get a 'retribution' kill, boosting their score significantly. After thirty seconds, or death, the cycle begins anew until one player reaches the required score limit.
According to Steve Polge's pre-match briefing, Betrayal relies heavily on tactics to boost scores as quickly as possible. In practice, gameplay deteriorated into a free-for-all within seconds in an effort to stay alive. Decisions to kill or ignore players are supposedly based on their scores, positioned above their heads, but in the heat of insta-gib battle, there simply isn't enough time to evaluate this information while dodging laser beams of death. The main problem with Betrayal, it would appear, is that one must kill, or be killed, making the mode feel somewhat superfluous when Insta-Gib Deathmatch already exists. Perhaps, in time, clans and gamers will 'get it,' but in the short time available to us, we certainly did not."
"The other new game type is Betrayal. In this mode - played only with Instagib rifles - you're randomly dropped into a group of three. Every kill you make adds a point to your personal score (more, if the person is beating you), and a single point to your group's pot. When that pot's tempting enough, you can alt-fire on a team member (who glow conspicuously blue) to betray them, and claim the pot. This will make you a teamless rogue member for 30 seconds, during which time your former team-mate will get a heavy bonus for killing you back. The back and forth - especially on the claustrophobic and wintry map, Koos Barge - resembles the cut-scene after level two of Pac-Man. A little. Perhaps not enough to warrant saying it. Again, though: tactics were out of the window for the eight journalists in the Epic offices. Betrayals were made to claim an empty pot, with betrayal seeming fun enough to commit without cause or benefit. But a number of design decisions made the possibilities clear: the hunger for payback is strong when someone pips you to betrayal. And the decision to give the betrayal gun a different colour is a rudimentary stroke of genius. Normal shots are red beams, so if a blue beam sizzles over your shoulder, all loyalties should be considered dead. It takes a lot of discipline and misplaced trust to let that pot get to ten."
