Just bought and tried me some Insurgency Sandstorm, which is currently a beta, and I love it. A huge improvement over the previous game. Looks better, feels better, sounds much better, is more challenging, also a little more brutal. The way ppl drop looks incredibly realistic. Haven't seen ragdoll physics like that, also some limited gore. Just about the right amount, not overdone. Cherry on top are the moans, screams, situational comments and reactions of the AI ( both yours/allied and enemy ). Like when they are being surpressed, wounded or funniest to me when you're the only one left of your team, your character be like: "...oh shit ...." or ".... Do you copy ? ... hell, where is everyone .... !?" and that badass 'last man' theme start playing. ^^ Another cool feature is cosmetic options of your character and choice between male/female which feels much more natural compared to other games because the design is vaguely based on ongoing conflicts like Syria or countries like Afghanistan.
tl;dr - It's a lot of fun. Can definitly recommend.
