This game stands in my top 5 of all time. I'v been gaming for 19 years now, constantly. If you haven't played this game before..you should.
Go to bear pit forums and download the 1.12 Mod.. It adds hundreds of new weapons, new gameplay features and MERC's.. It makes a fantastic game even more so.
I'm not going to go into any detail over the game, buy it, experience it, love it.
