This is a very odd and and unique shooter, and surprisingly its gameplay has a lot of depth to it. This is basically the fast and furious of video games when it comes to its story, you go from fighting in ww1 to zombies invading then you kill a nazi scientist to become a necromancer and make zombies from enemies I kill tl fight along side me, then get into a titan mech and destroy castles for some reason, then you literally go to hell to fight demons, then fly on a flying on a dragon to fight satan in a demon mech robot. I love that you can have a knife in one hand and a pistol or smg in the other, so you slash and shoot at the same time, and with a dedicated kick button to knock enemies over. the "shadowhand" as they call it in the game is like a wolverine glove that after a few melee kills you can shoot an explosive projectile that is very useful (as well as having flame and freeze abilities you later unlock. Also you carry every single weapon and grenade type in the game so you can use whatever you want at any time. It that adds a lot of depth too since you have so many tools the game gives you. One disappointment from people who only played the first couple chapters of the game is the human enemies are frustrating , as there is very little hit impact or hit markers and they are not one shot headshots, making the fps experience at the start pretty bad, but after that point the game picks up and the zombies, vampires and demons are much better. It really feels like (for the zombies part of the game) they took COD zombies and gave it way more weapons, deeper mechanics, and more player ability. This game is still pretty buggy though, when you will collide with an enemy or object sometimes you will fly high in the sky and land back down taking fall damage, but with so much health you have, every enemy drops health and breakable objects containing health it issue and it makes the difficulty is balanced. The game will throw a lot of damage sponge enemies at you but you are also a damage sponge with a lot of guns and explosives. a few crashes will happen its just inevitable. Bosses are meh, they are pretty easy and there is much strategy to them other than shoot and side step attacks. The final boss is where things get really rough for the player. On the final phase as you fight satan, you can get easily stuck on the terrain. Overall its worth a buy, it starts off slow but it has a decent amount of gameplay variety and its a different fps experience than most out there. You can get steam keys for this game for less than a dollar
