This game reminds me of STALKER and STALKER:Clear Sky pc game. Same complexity, modding and world exploration. I do remember having to SAVE game progress every now and then as a crash would occur just like the in-game radiation storms. There were mod upgrades for weapons, suits, ammos; the game was fun and entertaining. My favorite body armor was a suit that used Servos with a choice of adding night vision goggles with a blue hue. Anyone who played this game will notice the similarities between these two.
