Space Invaders by Neave Games looks and plays a lot like the arcade original, although there are several minor differences. The firing of the invaders can be erratic; sometimes they will not fire for several seconds. The same goes with the UFO, as it can sometimes not appear for a long time, at other times two of them will come out in rapid succession. Instead of making a high-pitched sound when it appears, it has a very quiet hum on this version (which also most of the sounds are different as well). The bunkers do not ever get refreshed, the last invader on a level does not move quickly, the 300 point secret for the UFO is not present in this version, and the player earns an extra laser base at the completion of every level.
