MOVE
WASD to move, mouse to look, SHIFT to sprint, SPACE to jump. Click the arena to take the pointer; ESC gives it back and pauses.
TWO WEAPONS
1 BEAM — instant, endless, light. Hold to fire. 2 DISC — heavy, slow, and it bounces three times off walls. Three discs, one regrows every two seconds. Bank them around corners.
THE PROGRAMS
SENTRY walks and shoots. SEEKER flies fast and hits on contact. TANK is slow and hits hard. Every fifth wave a WARDEN arrives — big, patient, and it spreads its fire.
WAVES
Clear a wave, breathe for six seconds, the next one enters from the corners. Integrity regenerates slowly if you stop getting hit. There is no end; there is a best wave.
