I know very few will see this, but I must warn people that this game is just TERRIBLE! Here's is everything on why it's bad. The animations on everything is choppier and uglier than any 90's fps, the dude's face isn't even capable of smiling when getting the chain gun wannabe he just glitches out, the pistol doesn't even have a muzzle flash too, that's the kind of quality we are talking about here. The zombies have like two frames for their attack animation and that causes them to fire too quickly, this causes you to lose health very quickly even on easier difficulties. Every time you die the screen freaks out with red flashes twice before loading you back (90's style, with a pistol of course.). You can't play the rest of the episodes You can only play episode 1, I assume that the game is trying to get you to purchase them, but the developer's site isn't available anymore so that probably explains that predicament. The level design ranges from sub-par to infuriating, when you start the first level, there is already an enemy in front of you that is about to attack you, this will obviously catch you off guard so you'll wind up losing more health than you should at the start. Another bad thing is level progression, when you kill the final boss, its death animation glitches out and then that same boss reappears from that glitched frame so you'll have to fight the boss again to end the level. (The glitched frame is still around during the fight.) Also there are two levels in the game that requires you to find not slightly obvious secret push walls TO PROGRESS FURTHER IN THE GAME! The controls somehow managed to be worse than the iOS version of Wolfenstein 3D, your moving speed is so fast but the viewing speed is so slow, these controls are infuriating and disorienting. This game is just some low budget and bad quality Wolf3d lite mod that fails to be a good retro fps game. If anyone read to this point, do yourself a favor. DO NOT GET THIS GAME! (and thanks for listening to my pointless rant.)
