Unreal Championship 2 also uses a mechanic that deviates from the standard Unreal Tournament line of games, wherein each character has a designation of light, medium, or heavy, that determines the health, melee weapon damage, movement speed and agility of the characters. Light characters have the least amount of health and melee weapon damage, but are faster and more agile than the other types. Medium characters are in the middle for all three attributes. Heavy characters have the most life and melee weapon damage, but are the slowest and least agile of the three.
Another addition is the lock on mechanic, which keeps the locked on character in front of the player. While it doesn't center the enemy in front of weapon firing reticules, it does keep the character on the screen until either the player unlocks them, kills or is killed by them, or the locked on character is out of line of sight. This mechanic helps alleviate the imprecision of analog sticks on the console, as opposed to using a mouse and keyboard on the PC platform, especially when circle strafing and to make melee attacks easier to control.
Adrenaline use is unique to Unreal Championship 2, compared to other Unreal Tournament games. Each character has six adrenaline powers at their disposal. All characters have access to speed, which grants increased movement speed for a short time, and nimble, which makes characters float while jumping, and allows for additional jumps beyond the double jump. Each race in the game, human, Nakhti, Necris, Skaarj, Juggernaut, and mechanical, then each have their own race specific powers. Some characters also have unique adrenaline powers. Adrenaline is gained slowly throughout the match, but is gained faster for kills and killing spree awards. There are also adrenaline pickups on the maps. Each power uses a set amount of adrenaline to activate, ranging from one quarter of the total adrenaline meter, to needing a completely full adrenaline meter to use.
