Robotron in 3.5K... "Impossible!" I hear you cry - and you're right. That's why this version is called Minitron.

The characters are chunky and the robots overlap badly as they pursue you and the humans around. You automatically shoot in your direction of movement, but unfortunately there's only one species of robot enemy for you to blast.

The game is easy except at the start of a wave and I clocked up 500,000 in no time at all. More memory is needed to make this game really good.
