Your level is decided by your total XP. Every level costs 1.5x the one before it, so the numbers climb fast.

• W A S D move  ·  MOUSE look  ·  LEFT CLICK fire
• 1 to 5 swap guns, 6 to 8 quick items (or the numpad)  ·  R reload  ·  WHEEL cycles too
• E opens the pack  ·  the crosshair creeping a few pixels when your hand is still is the gun's hold, not a fault
• RIGHT CLICK hold to steady  ·  CTRL or double-tap W to sprint
• SHIFT hold to lie down  ·  SPACE jump  ·  B slide  ·  TAB scores
• Bots lie down too, so keep an eye on the ground as well as the doorways
• ESC pause  ·  CTRL + / this help

• W / A / S / D Move
• MOUSE Look

• SPACE Jump
• R Reload
• 1 – 5 / WHEEL Switch weapon (takes 1 second)
• 6 – 8 Use a quick item — health, shield or ammo

• A kill pays that bot's LEVEL, and a bounty for however long it had been up.
• Robots earn XP exactly like you do, so the more a bot has killed, the more it is worth.
• The roster and bot count are set on the lobby screen.
• Health comes back for everybody, so there is nothing to switch off.
• Hold RIGHT CLICK and you shoot harder and stay steadier; every shot lands a little slower than it looks.
