I'm a big STALKER fan so this game is really up my alley with the gameplay. It took a bit to get used to everything, but the game gets rather easy once you understand enough, which I think is fine. Once I finished about an hour session of clearing all enemies and areas, I actually felt like I played a real game, which is rare on this site, which is full of shovelware.
The sex is rather OK, I think the animations could benefit from the characters keeping their cocks inserted for more than 5 seconds before taking it out. I'm also not much of a fan of the oral sex noises, to me it sounds like she's trying to vomit.
Overall, I am very impressed, and I'm excited to see more from the game and developer; more creatures, new areas, new guns mayhaps.
