It's a generic unity shooter with horrible gun mechanics, (Really they are absolute garbage) and the Nazi's can seem like bullet sponges but no your bullets just miss half the time, also there's only one map which could get boring also location of all the memes is the same as well, there also no way to change your controls on anything as the only option in the main menu are start game and exit.
Ok that's all the negative points out the way.
So where to begin,
1. The game lets you run around killing Nazi's and who doesn't like to do that.
2. You collect memes and some of them are decent
3. Don't worry about aiming just run holding mouse 1 that should do the job better
4. also you get to kill priest Hitler so you can actually confirm his death (Couse Nobody can trust the Russians)
Basically what i'm trying to say is, this game is great you will probably die few times at the start but you will later realise that you can avoid combat until you get to Hitler, and it might take you a while to find the memes and it could be hard to maneuver around the map.
So if you want to play it i recommend using your smg and to hold shift at all time until you get to Hitler that combined with the knowledge of where all the memes are will make you beat this game in mere seconds, unless you decide to do a challenge like using only your pistol or melee only (Im not sure if melee challenge is possible i have tried it but died against Hitler every time i tried it, so if someone manages it pls let me know)

TBF It's decent now, still lacking a few features but overall Valve did a good job at bringing this game back from the god-awful state it was.
