It's pretty good, but the PC version is better.

User Rating: 9 | Final DOOM PS
I found this at my local game shop and decided to pick it up since I wanted to see the difference between the PS1 and the PC versions.
It is pretty good,.

The graphics are kinda bad, and you can't see as clearly as the PC version, but you can tell what key a door needs.

Multiplayer Mode is weird. You need two TVs, two PlayStation Ones, a special link cord, and two copies of the game. Why can't it be splitscreen? It's one thing on the PC, but another on the PS1 or any console. And I was really disappointed when I found this out, since my favorite part of any FPS is the Multiplayer.

In short, if you can find Final DOOM for PS1 cheap, buy it, since it can get to be expense on eBay. It's ok, but there are a few problems.

I give Final Doom 9.0/10

Also, I discovered you can use a mouse for this game. I never knew there was a mouse for the PS1. Cool.
