Roborun

Every wall in the room is electrified and kills on contact — you, the robots, everything. You move and fire independently in eight directions, but your shots do not destroy robots: they stun them, and a stunned robot rises again as a recruit that follows you and fires on the ones still hostile.

• Touching any wall is instantly fatal. So is a robot's bullet, or contact with a robot.
• Robots also die on the walls and on each other, so patience does some of your work.
• Openings appear in the outer border; stepping through one takes you to the next room.
• Linger and the Sentinel arrives: indestructible, passes straight through walls, and cannot be fought — only left behind.
• The Sentinel hunts your recruits before it comes for you, eating them one at a time.
• Clearing every hostile robot before you leave a room pays a bonus on top of the recruits.

• Desktop (Easy/Normal): WASD or arrows to move and face, Space to shoot along your facing
• Desktop (Hard): WASD to move, arrow keys to fire in 8 directions independently
• Phone & tablet: on-screen controls supported on touch devices

• A posse is bait as well as firepower. While recruits live the Sentinel is busy with them, which buys you the time to clear or leave.
• Recruit early rather than late. A robot converted at the start of a room fights for the whole room; one converted at the end fights for nothing.
• Fire along the gaps, not at the robot. Shots and robots both die on walls, so the shot that matters is the one with a clear lane.
• Know your exit before the Sentinel arrives. It ignores the maze entirely, so the only escape is an opening you have already located.
• Do not chase the clear bonus with the Sentinel in the room. It cannot be killed, and it will take the recruits you were counting on.

Roborun grows out of Berzerk, released by Stern in 1980, one of the first arcade games to speak — the voice chip was expensive enough that its vocabulary stayed small.

You move room to room through a maze whose walls are electrified, which means the scenery is as dangerous as the robots and a panicked retreat usually kills you. The robots shoot each other by accident, so patience is a legitimate tactic. And if you linger, Evil Otto arrives: a bouncing smiley face that passes through walls, cannot be destroyed, and simply keeps coming toward you. He is not a threat to beat but a clock with a face.
