Eco Fighters
Capcom decided to make an arcade “shmup” with an environmentalist science fiction theme. The result was Eco Fighters, a very well made game with one massive flaw. And no, the massive flaw was not the environmental theme. The massive flaw has to do with how you aim.
See you control a spaceship that has a rotating arm/turret. It sounds good, but in practice it’s a gimmick that’s hard to work and control. This and the fact that you’ll often unavoidably run into a weapon change that you don’t want (which gets rid of something you do) sours it a little.
But only a little. It’s still a good side scrolling spaceship shooter, and the graphics and music are typically excellent for the time period. It just tried something distinct and fell short in that regard.
