Evade guards, collect the secret file, and escape through the gate on six routes. Optional supply boxes provide extra intelligence and 6 battery, but reaching them takes you closer to patrols.
Move with WASD. RETURN switches between normal and quiet walking. Normal steps cost 1 battery; quiet steps cost 2. Normal footsteps can be heard by guards at a distance below 5, while quiet steps are heard only below 2.
Directions work on the keyboard or pad; the pad button also acts as RETURN. SPACE opens confirmation to restart this stage. NO is selected initially. Choose with A/D, confirm with RETURN, or cancel with SPACE. Play pauses during confirmation. CTRL+C returns to BASIC.
Your character and guards turn and move through intermediate positions. Dots mark the extent of your footsteps. Supplies, the file, and the gate have different shapes. Detection freezes the scene and its cause. Wait for animations to finish before pressing again.
BATTERY shows power remaining, QUIET the walking mode, FILE the required secret, and INTEL optional information. Carry the file into the gate to clear the route. Guards respond after you move, so weigh approaching patrols against the battery cost of staying quiet.
