Cheats performed on BZFlag are usually made by modifying your client. A great deal of power is invested in the client program, and therefore the client may cheat in every way from creating invincible tanks, to invisibility, to super killing. If you have seen any cheats, have performed them yourself, or have noticed a hole in the source, please add it here. Preventions for many of these cheats are being developed for inclusion in v3.0.

Warning

Do not use a modified client on a public server. If you are found to be using a cheat client, you will likely be banned from multiple servers and could quickly find yourself with nowhere to play. Cheating in BZflag is not the same as using a cheat code in a PlayStation game. See also the Notes on "CHEAT" servers at the bottom of the README, which forbid the hosting of a "cheat" server. A copy of the README is included with the source code and is displayed when you install a pre-compiled copy of the game.

Blatant Cheats

The following cheats are considered "blatant" cheats because they are usually apparent, even to new players.

NOTE: Some of these cheats may be prevented or already fixed in certain versions of BZFlag.

A cheater may:

  • fly without Wings.
  • steal from or give flags to other players.
  • give flags to observers.
  • rapidly pickup and drop every flag on the map, as if a flag reset were performed.
  • spawn with a flag (usually Guided Missile or Genocide, but can be anything).
  • be immune to the effects of bad flags.
  • grab a new flag when passing through a teleporter (when no flag exists).
  • move, pickup flags, or shoot other tanks while paused.
  • move through buildings without Oscillation Overthruster ("wall walking").
  • move backwards through buildings with the Oscillation Overthruster.
  • drive outside of the playing area.
  • jump back briefly to avoid a bullet then return to where you were ("network jitter").
  • double jump.
  • move vertically on a map very quickly or higher than settings would normally allow.
  • instantaneous travel to a new location.
  • jump and land at a pre-determined set of coordinates (i.e. the center of a team pad).
  • shoot teammates without blowing them up.
  • shoot bullets that travel at a different rate (usually faster).
  • shoot bullets that travel at impossible linear paths (i.e. downwards, sideways).
  • shoot bullets from any side of their tank.
  • fire multiple shots simultaneously, often in spreads & separate impossible paths.
  • shoot bullets which cannot be seen on radar or in the HUD.
  • cause himself to be shot by any other player, even if no shots were fired or the player hasn't spawned (AKA "TK Cheat").
  • cause another player to shoot the cheater, even if no shots were fired.
  • produce abnormally long laser blasts (in terms of length and time).
  • be zoned, but yet still shoot tanks that are not zoned.
  • become instantly unzoned.
  • not lose flags when paused.
  • cause the bullets of other tanks to explode prematurely.
  • lock onto stealthed players while using Guided Missile.
  • produce abnormally large, small, or frequent shockwave blasts.
  • produce shockwaves at several locations simultaneously.
  • respond differently to gravity.
  • move at a different rate (usually faster).
  • instantly self-destruct.
  • be completely invincible to shots ("god mode").
  • be invincible while on auto-pilot.
  • be partially invincible, repelling everything but some particular flags (often SW or SR are chosen).
  • instantly kill everyone else.
  • spawn without delay or very rapid respawns (Has been fixed in 2.0.11).
  • be joined as an observer, but playing with a visible, invincible tank
  • be able to strafe or slide left or right
  • send chat messages that appear to have come from another player

Subtle Cheats

Subtle cheats are modifications to the BZFlag client that give the user an unfair advantage. Unlike the obvious "blatant" cheats, these modifications are often difficult to detect by other players. These modifications often involve small changes to existing source code, and will make their users appear luckier, more intuitive, or more accurate shooters, giving them a slight edge.

Some of these cheats may be detected by examining long-term player statistics. For example, if a specific player picks up a certain superflag 80% of the time over an extended period, on a map where flag positions are completely randomized, then there is strong reason to suspect the player of using a flag identification cheat.

The following is a list of known subtle cheats:

A screenshot taken on a typical cheat client. Various modifications and enhancements are visible.
A screenshot taken on cheat client.
FlagColoring
Flags are given unique colors (or some other identifying feature - colors are simplest). This can be applied to some, or all flags. For example, bad flags are brown, Shock Wave is cyan, Stealth is orange, Guided Missile is pink, etc. This allows the user to avoid bad flags, spot good flags from across the map, and tell what flags other players are carrying or picking up much more easily.
RadarPath
The player can see bullet trajectories at an extended length, making shots easier to avoid, or aiding with targeting. The latter function is used mostly on ricochet maps.
StealthDetect
The player can see stealthed tanks on the radar. Often times the cheater's client will flash the stealthed tank on the cheater's radar. This allows a cheater to know that he shouldn't be able to know that tanks position and allow him to "play dumb".
CloakDetect
The player can see cloaked tanks on the field. Often times the cheater's client will show cloaked tanks as zoned tanks (as if holding the PZ flag).
DisableBadFlags
Bad flags whose effects are invisible to other players are disabled from affecting the tank.
NoGenocide
A teammate is impervious to Genocide.
FunnyBullet
Various cheats that affect the manner in which bullets are fired are possible. The simplest is to increase bullet velocity. Other cheats include launching multiple bullets in different directions and giving bullets a vertical slope. Many of these cheats are less subtle, and discussed above.
SkinnyTank
Normally, if your aim is a little bit off, you can still kill a tank. When this cheat is in effect, other players have to aim more accurately to kill the user.
ImprovedConsole
The player's console provides more information than is normal. It's debatable whether this should be considered a cheat or not, but players with better consoles will have a slight advantage.
GuidedMissileWontUnlock
When the user is killed, his guided missiles remain locked on their targets. This is harder to detect than a Guided Missile being able to lock onto stealthed players, which is discussed above.
A hacked client equipped with the ProgressiveIdentify cheat. One flag has been identified so far.
BulletFreeZone
Any player in the game can cause anyone else's bullets to explode prematurely (if their client is hacked). Here are a few possible effects:
  1. A victim (or victims) will not be able to fire his weapon (bullets will explode shortly after leaving the muzzle). Others can't tell who is causing this.
  2. Bullets will explode before hitting a cheater, as if the cheater has a forcefield.
  3. Bullets will explode before hitting a "victim" who is not the cheater, creating the impression that the victim has a forcefield and is cheating. Or the cheater could create the impression that a whole group of tanks are cheating.
  4. Bullets will not be allowed to enter a "bullet-free zone" (such as a building or platform).
TinyCloak
The cheater's tank is modified to be smaller and harder to hit, but only when carrying the Cloaking flag. Making a tank this hard to hit would be a blatant cheat if the tank wasn't cloaked.
ProgressiveIdentify
A variation of the FlagColoring cheat. The client holds the identity of each flag in memory whenever it is picked up by any player and displays the flag type on the cheater's HUD.


In addition to the above subtle cheats, a cheater may:

  • have a wider than normal field of vision (e.g. 120 degrees)
  • have Guided Missles modified to not lock onto team mates
  • modify the turn rate of his Guided Missles
  • modify the way his targets are selected for Guided Missle lock
  • have an indicator showing when an opponent is in reloading mode
  • modify his client string
  • automatically self-destruct if a geno bullet comes too close to him
  • see the screen and radar when paused
  • be able to see who locked on them with a Guided Missle
  • have radar or different radar settings independent of server radar settings
  • have lines on the radar showing which way each tank is facing
  • see burrowed tanks as regular tanks on the radar
  • have no limits imposed upon the radar "/set _radarLimit 0 or Burrow do not affect the radar"
  • have shots by a zoned tank not show up on radar
  • make slight turns when falling
  • have different binocular zoom settings
  • fire with no delay after stealing a flag with thief
  • have an indicator showing how many wing jumps are left
  • see invisible bullets on radar
  • see opponent's team color despite opponent having masquerade flaga
  • have an auto-aiming ability that lines up on other tanks to fire upon
  • be able to enable auto-pilot on non-auto-pilot maps
  • be able to enable/disable/enable auto-pilot without delay
  • be able to enable auto-pilot without notifying the server/other players

Other Malicious Activities

The following is a list of malicious activities that cheaters might also engage in:

  • attempt to guess or "crack" the server or map's password.
  • the use of "Bots" or "Drones" to lag a server by sending large amounts of data or using client commands rapidly
  • the use of "Bots" or "Drones" to deny a poll or create and complete a poll in the favor of the cheater
