Game play isn't difficult. The screen position of the pray can at the lower edge of the monitor changes only in movement from left to right. Constant firing is hard, as the spray seems to come from the unit in bursts. Firing at the falling, flying and diving insects is important, but so is dodging the hail of return fire. Once a pattern for successful defensive movement is found, the offensive maneuvers seem to take care of themselves, as long as the player keeps firing.
The colors are the best feature of this game. Sounds are about average, as is gameplay. For the novice player, Spider Fighter is a nice intermediate-level action game that brings decent enjoyment without corresponding levels of frustration. But 2600 players who are familiar with Activision's usual efforts (which are exceptional overall) might feel a bit let down by Spider Fighter.
