Hostile Intent
Release and new site later today, if anyone still plays halflife or steam you should download it and we'll play. May not look like much from the screenshots, but i beta tested it for a while and its a damn realistic experience. Looks pretty good for the hl engine too.

Isnt this the mod that came into being once cstrike went ass, i mean, retail?

It's been going for years now with no release due to team problems and such.
its more on the realistic side, but still maintains fun gameplay.
It's been polished and stuff since I've played it alot, but even in its basic form it blew me away.
