Cooperative

Cooperative mode, you are able to play with your friends and fight against the hell spawn's of doom. In this game mode, you can be able to respawn back into the game if you die.

Survival Cooperative

Survival is just like the Coopertive game mode, however in survival, if you and your friends die before exiting to the next map, you lose. Survival is more like Last Man Standing, however for cooperative.

Invasion

Invasion mode, you will fight against a swarm of monsters, and in each wave, you will have even more monsters to fight with! Don't think that this is easy all the way through, it will get harder and tougher when you get passed the first or second wave!

Deathmatch

The classic mode of play we all know and love. Simply put, players run around and attempt to kill (frag) each other. When a player dies, he respawns, and resumes trying to frag other players. Generally, a fraglimit is set, and when a player reaches that amount of frags, the level ends.

Deathmatch modes that are played in teams should not be confused with Teamgames. Those are discussed in more detail later in this article.

Team Deathmatch

Team Deathmatch splits everyone into teams; and you and your team must frag the opposite teams! Team Deathmatch is exactly the same as Deathmatch, however you are playing under teams.

Duel

Duel is basically One-on-one deathmatch. Two players fighting against each other on the map, while the other players wait in line to play the winner. To win in a duel game, you must frag the other player by reaching the frag limit.

Terminator

In the Terminator game mode, the Terminator sphere will be spawned at a random spot. Once a player has picked up the ball, that player will be the Terminator! The Terminator will have 200% Health, 200% Armor (Just like a megasphere), and have permanent quad damage! The Terminator can easily be found, by the Terminator Icon on top of the player's head. When the Terminator is killed, the player that killed the Terminator will gain 10 frags, and the Terminator ball is dropped; allowing other players to pick up the Terminator ball, and being the next Terminator!

Last Man Standing

Last Man Standing is somewhat like Deathmatch, however with a few differences; you will have all the weapons you will need (Excluding the BFG's), and you have to be the last player alive. In last man standing, you gain points for being the last player alive for each round, unlike deathmatch; where you win by frags.

Team Last Man Standing

In Team Last Man Standing, the rules are still the same from Last Man Standing, however the players a split into teams. The last team standing, wins a point!

Possession

In Possession, a Hellstone will spawn at a random location; when a player picks up the Hellstone, the player must stay alive for a certain time length to gain a point. However, there is one minor draw back; you will lose all of your weapons making you completely defenceless! If the possessor dies, the player will drop the Hellstone, allowing another player to pick up the Hellstone.

Team Possession

Team Possession is exactly the same as Possession, however; when someone on your team obtains the Hellstone, you can help defend your possessor from the other team. If the player dies, again the Hellstone will drop; however any player from any team gain pick up the Hellstone.

CTF

CTF or Capture The Flag, you and your team must pick up the flag from the other teams base, and carry the flag back to your team's flag to gain a point! However, don't think it is that easy; while it might sound easy, you still have to defend your team's flag, make sure that your carrier safely scores a point for the team. If the carrier dies, while holding the flag, the flag will be dropped allowing anyone from the same or different team to pick it up, and try to score a point, or the flag will return back to it's base.

One Flag CTF

Very similar to CTF mode, except a third (white) flag spawns in the middle of the map. Instead of bringing your opponents' flag back to your base, the objective here is to bring the white flag to your opponents' base.

Skulltag

Skulltag, commonly abbreviated "ST," is a game mode very similar to CTF. However, there are a few key differences. First, skulltag uses skulls instead of flags as the main possession of each team. Second, instead of bringing the opponent's skull back to your skull to score a point, the skull must be placed, or "tagged," on a score pillar located somewhere throughout the map. This decoupling of flags and return spots creates an interesting, complex gameplay experience. Multiple score pillars for a single team can be placed, score pillars can be worth varying numbers of points, and score pillars can belong to either team, or both teams.

The idea of the skulltag game mode is what originally lead to the creation of the port, Skulltag. For more on this, see the section on Skulltag's history.

Modifiers

Buckshot

This modifier restricts players to use only the Super Shotgun! Fast paced close combat is guaranteed.

Instagib

Everyone starts with a railgun, without anything else spawning on the level. Of course, in this mode, the railgun is so powerful, it will kill you in one hit! Not only that, but it will do so much damage when it hits you, will you gib instantly! (thus the name, "instagib") Quick reflexes and high accuracy are essential for winning in this fast-paced mode!

Teamgame

Standard vanilla modes where players are broken apart into teams. When you play with a game file that has it's own heavily scripted game team game, you want to check the game file text or website for instructions on how to play the game.
