Is it possible to make material penetrateble ? . i mean like penetrate a concret wall and kill the guy behind it ?. i know it works with some walls inte the game but not all . Or another thing if i use a M107 with armor piercing rounds is it possible to penetrate 2 guys . lets imagen that one guy stand right behind the guy i shot on is it possible to change the flesh material so i kill the other guys too . That is what happends in real life of you shot with armor piercing rounds . it would be nice if someone can make it possible for the game as well .. Or if someon can inform me how to make it possible .
