Berzerk - 1-bit hack

[e1will]

This is a hack of Berzerk that changes the individual robots into "Halo 2600" style enemies: 3 copies of each; destroying one destroys all three.

 

Since three robots means three bullets, the second and third robots on each line will "disappear" whenever the first robot shoots horizontally so that they're not hit by "friendly fire." But beware, as soon as the horizontal bullet hits a barrier, the second and third robots will reappear.

 

(It's called a "1-bit hack" because I changed only one bit: The "5" at location $f1c9 was changed to a "4".)

 

Enjoy!
