The game also features mild violence. Much of the violence is between spacecrafts, with no clear sight of damage or injury to the pilots inside, although the player can also shoots at alien creatures. The reactions to violence are not realistic, with enemies flashing when hit and disappearing in explosions when defeated. Damage is indicated largely via ‘hit’ points, which contribute to the player’s score, although some alien creatures do show puffs of ‘blood’ which disappear into space.
