When shot, larger asteroids break apart into smaller pieces and fly in random directions, while the smallest asteroids are destroyed when hit.

", a cluster of ships that break apart and chase the player's ship when hit. Objects "wrap" from each edge of the screen to the opposite edge (e.g. from the right edge to the left, or the top edge to the bottom), as in the original.
In addition to the shield feature and the Killer Satellite, the most significant change in this version of the game is that the flying saucers can now target the player's ship across the screen boundary - meaning that if the saucer is close to the left edge and the player is at the right edge, the saucer may shoot toward the left edge and across the boundary to hit the player since their ship is closer that direction. In ''Asteroids'', the saucers could only fire directly at the player's location on screen without considering the boundary, which led to the popular
"lurking" exploit that enabled players to play for very long periods of time on a single credit. This updated strategy was in direct response to that exploit.
