The martian is a respawning monster. There are two different types of martians: normal and top of screen.

Behavior

Normal martian

Normal martians will try to stay about 70 pixels away from a target, while lining themselves up for a shot on the target. However, the relatively large amount of time between direction updates means that they generally just dart around diagonally in the vicinity of the target.

Every frame, attempt to shoot at a player or victim if there is one within 8 pixels of the martian on a single axis. Every 61 attempts, a shot will actually be fired.
- When a shot is fired, stand in place for 12 frames.
Every 61 frames (about once per second) update the movement direction:
- If the nearest target is less than 60 pixels away, move away from the target.
- If the nearest target is between 60 and 79 pixels away, move in the direction of the shortest distance to line up with the target on a single axis.
- If the nearest target is between 80 and 223 pixels away, move towards the target.
- If none of the above is true and there is no player within 207 pixels on a single axis, then despawn.
Move in the current direction at a speed of 1.5 px/frame.

Note that martians will target decoys, but they will not attempt to shoot at them.

Top of screen martian

Top of screen martians will move side to side above a target, trying to maintain about 108 pixels of space vertically. Upon spawning, they will set their Y position to 8 pixels below the top of the screen.

If there is no player within 207 pixels on a single axis, despawn.
If there is a player above the martian, convert into a normal martian.
Every frame, attempt to shoot at a player or victim if there is one within 8 pixels of the martian on a single axis. Every 61 attempts, a shot will actually be fired.
- If a shot was not attempted in this way, randomly attempt to shoot down with probability 30/256 (about 11.72%).
- When a shot is fired, stand in place for 12 frames.
Every 33 frames, update horizontal movement direction:
- If the nearest target is less than 20 pixels away, move away from the target.
- If the nearest target is 20 pixels or more away, move towards the target.
Move based on the current horizontal movement direction:
- If the nearest target is less than 96 pixels below the martian, move up-left or up-right at a speed of 3 px/frame.
- If the nearest target is between 96 and 119 pixels below the martian, move left or right at a speed of 1.5 px/frame.
- If the nearest target is 120 pixels or more below the martian, move down-left or down-right at a speed of 3 px/frame.
