Adrenaline is a power-up system that is part of UT2003, UT2004, Unreal Championship, and Unreal Championship 2.

UT2003, UT2004, and UC

Adrenaline can be collected by picking up adrenaline pills scattered throughout the arenas, or by achieving certain goals, such as killing opponents and capturing flags. It was originally thought of to allow breaking through stalemates in team-based games.

In UT2003 pills give the player 3 Adrenaline points, whereas in UT2004 they give the player 2. Adrenaline doesn't feature in Last Man Standing, Onslaught and Assault. Because Adrenaline adds a certain amount of randomness it is often manually disabled in competitive games. A notable exception is TAM, where adrenaline is a key part of the strategy.

Once 100 Adrenaline points have been collected, the player can start an "adrenaline rush" by quickly executing a sequence of movement keys. This rush will give the player an advantage, but only for a limited amount of time. If the player carries the flag or bomb in the relevant gametypes, the amount is shortened.


Below is a list of methods of gathering adrenaline, and the associated amount gathered.

  • Get pill: 2 (in UT2004, 3 in UT2003)
  • Frag in DM/TDM: 5
  • Frag in CTF/BR/DDOM: 2
  • First blood: 10
  • Spree: 10
  • Ending enemy's spree: 10
  • Multi Kill: 10
  • Death: 0
  • Suicide: -2
  • Frag Flag/Bomb carrier: 10
  • Return Flag/Bomb: 5
  • Capture Flag/Bomb: 25


Below is a list of combos showing the key sequence needed, an estimate of the amount of time the rush lasts in seconds, and the result of the combo. "Pint-sized!" and "Camouflaged!" are additional combos than become available through official mutators included in an Epic bonus pack.

  • ↑ ↑ ↑ ↑ Speed - (18) - Move faster, jump higher, drawing yellow tracks with your feet. In UT2004 this combo lasts half as long as most. It drains even faster if you are carrying the flag in a CTF or VCTF game.
  • ↓ ↓ ↓ ↓ Booster - (27) - (Re)generate health up to 199%, then shield up to 150%, by 5 points per second or so. The player will emit green crosses.
  • → → ← ← Invisibility (27) - Turn invisible, albeit it with some shimmering effect
  • ↑ ↑ ↓ ↓ Berserk (27) - Increases rate of fire and knockback, including that of the Shield Gun, allowing its user to jump much higher with it. Three orange lines revolve around the player.
  • ← ← ← ← Pint-sized! (27) - Become half as big; disables crouching.
  • → → → → Camouflaged! (40.5) - Projects a, usually very conspicuous, holographic object around the player. The object depends on the static meshes used in the map.



  • Unreal Tournament 2003 had an adrenaline combo Superjump! that was added to compensate the loss of the Jump Boots in UT2003. For unknown reasons this combo didn't make it to the full release.
  • The unused announcement Berserker! might have been planned to be announced after excessive use of the Berserk! combo.


The adrenaline system in Unreal Tournament 2004 was originally intended to be a lot more complex, quite like the one of Unreal Championship 2. The unused announcements still remain in the game and reveals the combos that were planned but never made it:

  • Confusion - unknown, maybe confuses enemies by showing multiple players instead of one.
  • Holograph - probably was replaced by the Camouflaged combo.
  • Invulnerable - makes the user invulnerable, like Invulnerability in UT3.
  • Low Grav - should work somewhat like the Nimble combo in UC2, just simply makes the user low gravity.
  • Retribution - kills or damages the user's killer after death. Probably like the Vengeance relic.
  • Silencer - makes the user absolutely silent and harder to detect - weapons and footsteps can't be heard (works a bit like the Acoustic Dampener in Unreal.
  • Whirlwind - unknown, maybe summons a destructive whirlwind that works like the Gravity Vortex of ChaosUT2.
  • Loaded - the user regenerates ammo.
  • Lock on - makes all user's weapons homing.
  • Vampire - health taken is transferred to the user. Replaced by a mutator.
  • Instagib (questionable) - gives you the Super Shock Rifle for a small amount of time.
  • Burn out (questionable) - unknown, maybe makes you incendiary or works like the Vengeance relic.
  • Lock and load (questionable) - unknown.
  • Pile up (questionable) - unknown, maybe summons some team mates to the same area.
  • Rage (questionable) - unknown.
  • Sudden death (questionable) - unknown, maybe makes all the players low on health.
  • Totalled (questionable) - unknown.

Unreal Championship 2

The Adrenaline system was rethought for Unreal Championship 2, and plays a much more important role in combat situations, because it can be constantly used. The majority of adrenaline abilities are only using 50% of your adrenaline bar, while the bar refills itself automatically. Adrenaline pick ups are shared in the same proportion as ammunition, while one pick up fills 10% of the adrenaline bar. There is also a Super Adrenaline power up, which gives you instantly 100%. Killing opponents, capturing the flag in CTF games, delivering the ball in Overdose or rejecting shots also scores you some extra adrenaline. Adrenaline abilities can easily be activated by a small ingame menu.

The different characters have different kinds of abilities available to them, partly dependent on the character's race. Every character has six abilities in total, two default abilities, three abilities depending on the race and one character specific special ability. Race abilities mostly include one defensive, one healing and a hunting ability. There 38 adrenaline abilities in total:
