Realism mod. Now game looks more realistic and harder than ever. In most cases, without cover you will be nothing. Prepare to get shot by mercenaries even through metal sheets. Experience unscouted guard posts on the road and an RPG rocket flying at you or mortar, while you're in sniper's position.
Heavy update. Changelog in "ReadMe.txt" file. Starting new game highly recommended. Special thanks to LonerStalker, fitzjcol, McLovin.
