The Quake 3 total conversion mods Enemy Territory Fortress (ETF for short, formerly Q3F) and TrueCombat (known as TrueCombat: Elite in its ET incarnation) have been ported to Enemy Territory. Other mods, which consist of little additions and fixes to the game mechanics rather than a total conversion, include ET Pro (used in competitions but also popular in public play), ETPub, Jaymod, No Quarter, and Wolfenstein: The Frontline (although the current release still has the original name of FalckonET).


Cheats

Like many other multiplayer online games, Enemy Territory has cheats available on the Internet. The most common cheats are aimbots and wallhacks. Both of these cheats dramatically improve a player's performance, thus potentially giving a competitive advantage over other online players. However, players using these cheats can be difficult to distinguish from very skilled players. The easiest way to see if someone is cheating is to become a spectator, which allows you to look through a player's eyes while they are playing. The 'inhuman behavior' associated with inexperienced or blatant wallhackers and aimbotters can then be observed, and appropriate counter-measures taken. However skilled cheaters, using private or personally coded "hacks", proper settings and an elevated skill level can and do routinely cheat on ET.

Enemy Territory uses a program called PunkBuster to reduce cheating. The PunkBuster client can be updated within hours of an exploit or cheat being discovered, and thus forces cheaters to periodically update their cheats. ET Pro also includes an additional anti-cheat system, that is meant to be used in combination with PunkBuster. Both anti-cheats can be bypassed however.

Problems with PunkBuster can often be solved with help of the PBSetup utility.


Trivia

In the game, the Allied troops operate under the American flag, with American-style uniforms and ranks (regardless of whether, historically, the campaign alluded to was fought by British or other troops, as in North Africa). The only exception to this is Covert Ops, who wear contemporary British 'Commando' style uniforms. Axis troops use German-style uniforms and ranks and sound effects describing their actions are rendered in English with exaggerated German accents, however, some of the basic radio messages are in German. Still, they do not use the Swastika, but a special Wolfenstein flag, possibly because id Software has had games prohibited before in Germany because of the use of Nazi symbols (see Wolfenstein 3D).

The maps are either based upon real projects (Railgun -based upon the Schwerer Gustav-, Seawall Battery, Würzburg Radar) or films (Goldrush). Fueldump is a modified version of the RtCW single-player level 'forest'.

Sealab 2021, an animated television series shown on Cartoon Network's late night Adult Swim block, made reference to Wolfenstein: Enemy Territory in the episode "Hail Squishface" (Broadcast November 10, 2002). One of the characters, Debbie, requests ammunition for her firearm in the same fashion as a Wolfenstein: Enemy Territory player. She announces "I need ammo" as a bullet icon hovers above her head.


Slang

The following terms are common gaming slang, to include Enemy Territory-specific phrases.

* Arty Spamming, When a player continually applies artillery support onto an area, usually at spawn points.
* Backrage or Backrape, Being killed by someone behind you. This then developed into the derivatives 'siderage' (killed from the side) and 'facerage'. The original derivation of rage is used interchangeably with 'owned' or 'raped' (for example, "If you're getting backraped, go prone!")
* Beta Trash, A term used by North American players to describe weak players. The term comes from Team Warfare League.
* Corner Camper, A player who leans around corners waiting from other players to approach. They remain invisible to their intended victim.
* CP, Command Post.
* Gib, To severely destroy the opponent's body parts or fully kill them so they have no chance of being revived by a medic. It requires as much damage as the killing itself - typically 7 or 8 bullets from a submachine gun or two backstabs. If the body is gibbed by an explosive, there is no chance for a covert op to steal the uniform.
* Hax, Hacks
* pro Stick, A mocking word used to describe rifle-grenades (and sometimes panzerfaust), usually by those opposed to the appearance and use of them in game.
* pro Tube, Similar to pro Stick, but applied to the panzerfaust. Often people say "stop noobing me" if they get killed by
