Alien 3 on the SNES looks nice and sounds nice. The music in partiuclar.
However, the gameplay is really, really, slow. The jump feels like you're on the moon.
You have to do the same missions each level. Welding, killing eggs, rescuing certain prisoners, and then you have to go back to the terminal to complete said mission and get another one. It gets very repetitive.If the game moved at the pace of Super Metroid, I think it would be much better.
The Genesis version honestly plays much better.
Any version, though, is hard as ballzzzz.
Though the SNES version does beat any other verison for one reason;
