From the grafic/art of this game, you can compare it with "Heavy Bullets".
Its pretty simply "3D" poli-grafic and each time you play it is random - like Heavy Bullets.
But i like it a bit more than Heavy Bullets coz it doesnt have this "suddendly" moments. Each room you enter you can see already the enemy(s) spawn points as "black eggs" so you know if you go into the middle of the room (so thats the point that those enemys will...."hatch") you know exactly how many enemys it will be (mostly around 4 in each room).
I love the art of this game and the grafic fits pretty much. It plays pretty good and the enemys are really unique. The weapons are more or less "well known" like a shotgun, flamethrower or a cannon. You also can nicely mod them if you find one of those or buy ones from the stores in the game. The difficult is also nice, not to hard, i would even say still a bit "to easy".
Sadly after you know "how unique" the enemys are they are pretty easy to deal with and you can see already how many enemys will spawn if you go into the middle of the room. Also, as i said, the weapons are "well known" means sadly also it is nothing new. Next to this feels the beginning weapons, the revolver pretty much like a ol´classic 48-revolver out of the west. Ok, to be fair, you can mod it but at the beginning, its slow....and it IS slow as f*ck. Also the difficult doesnt get pretty much higher. Ones you have a good run (like i did with a full over mod revolver) you can finish every enemy with one shot and just shoot them in the face - i did it in one hour.
FS is a nice first person shooter but it misses a bit of content. The main idea is nice but you maybe should add things like different characters which starts with different beginner weapons, a bit like "Binding of Isaac" maybe. Also you maybe should "rise" the difficult a bit, JUST a bit, coz it is really waaaaay to easy. Next to this should maybe enemys drop more health.
I like it still but i must be THAT honest that i got the game in early access, so things can still change and i HOPE they do. Just add and change some things here and there and i bet FS will be even more funny as it is already.
I give it 7 points out of 10 so far.
