This one has some generic action music while you play but it's not break with sound of weapon and voicelines (.. bdw voices sound funny and the are not eng, but here you have proper subtitles and some poor tutorial so not that bad.). So it get the first PLUS for that.
Optimalization is just good enough, some adjustable options are in game, but they are in game. And that gives game another PLUS.
Cinematics are ok, they not breaking or interfere with gameplay and transition to gameplay is ok, witch again is rare in third party games. So another PLUS for that.
AI of enmies is maybe not stupid but very very poorly coded and linear, it's work just ok as simulation of fps ai if you play on rules puted by autor, but otherwise is gone stupid and can break. For that it get fat MINUS.
The grapical effects, reflections, flares and light works ok, and plants even as just plain as assets are quite dense and they are acceptable. It's not triple AAA game and it looks much better than moded FarCry1 (Imo FarCryBetaRestorationProject are nuts!). But still this game are far behind modern standard of games, and it is definitely low budget one at leat it looks like one of that. And for that I pass this time on giving plus or minus.
I seen much much worse games in all this aspects I write above, and this game for all it's pros and cons can get decent for what it is 3/10. But sadly this game has very very greedy developers, and at least on my country this game are overpriced equaly to the price of "PowerWash Simulator" witch in this case is just much much better game. And for that alone game deserve 0/10 and kick in the devs ass, but yep we are here on igg so to be fair we stay on 3/10.
