I reckon a Rambo game could be great, a bit of survival, some stealth and close combat as well a shooting. How on Earth a game like this one even gets released though, I have no idea. At any point did the developers sit down and think "fuck yeah! We are making an awesome game, just look at how pretty it is!" and at what point did the publishers say "yep this game is ready for release, lets make some money!" I mean seriously, this game looks like I made it. There are hundreds of total conversion game mods better than this.
How can anyone think they had made a decent game? They are either the most self deluded people ever or they knew they where scamming and throwing out any old pile of shit to see if any sticks, I wouldn't be surprised if they started advertising DLC for it or even season passes.
Its a sad illustration of just how bad the gaming industry can be.
