This game is one of the funnest games I have played in a long time! I absolutely love this game. I play on xbox so take that for what you will. Some prefer shooter games on PC. Well me personally, I think there is a reason why Modern Warfare is one of the most successful games of all time and is on xbox.
On to the game play. The campaign is sweet. I play on hard only cause I'm cool like that. The campaign was indeed hard at moments and stupidly hard at others. I say that only because of some of the design elements of the game. As someone who originally wanted to design games, I tend to spot these things with regularity. Example number 1 : while enjoying smashing face with a thunder hammer and quite enjoying myself, I died several times to stupidly accurate rocket fire.....from orks!!! Now heavy fire like that is supposed to make the game hard I know and make you move around to avoid it. It was just something that nagged at me because of fluff. Orks just are not that good at shooting, so why in this game are they deadly accurate with their rockets? I started to learn how to time the dodging of the rockets or take the time to take those out first so not a game ruiner at all, just kind of peeved me is all.
As a 40k player, this game has an astounding amount of detail in it. Anywhere from the sound you make when you run to weapon sounds. It's just amazing. Almost everything you do in the game functions like you imagine it would.
The fun wrought in the campaign was just Delicious! Things the orks say and do are hilarious. When you throw a grenade at them they scream, "Oh no, stikbomb" and run away from it! haha. The executions in the game are violent as all get out but I think any normal person won't be bothered by it. I thought they were cool as hell. Some of them made me giddity. For me, I know it's just a game and I get to act out this side of my imagination. You get to take the thunderhammer and use it like a baseball bat to the nobs, it's awesome! Also, suplexing chaos marines and then smashing them to bits is frakking sweetness!
Multiplayer is stupendous as well. Imagine a cross between gears of war, halo and call of duty. Third person shooter, your armor = your shields basically and you gain experience towards leveling up and unlocking perks. You play as either a Space marine or Chaos marine. This is chosen randomly depending on what team the computer assigns you to, similar to terrorist or marine in Modern Warfare. If your in a party and you join a new game the computer seems to randomly assign the group to fill spots in the ongoing game, so you can find yourself killing your party members. Quite amusing :P After the first game though, you get assigned teams together which is fine with me.
The game play in multiplayer is really fun for me. There are many different ways you can play. There are three main classes - Tactical, Devastator, and Assault. Within these classes there are lots of different weapon loadouts you can choose from. Once you have unlocked them that is, and it doesn't take too long at all. By level 20 you have unlocked all the different types of weapons. You can also choose to specialize in your weapon of choice simply by playing it more often and getting better with it. There are two perks you can unlock for each weapon mostly. Those perks make you do more damage or have more ammo for example.
The balance needs to be tweaked slightly but not too much I think. There is a semblance of paper vs rock vs scissors in Space Marine. Where the Dev is a rock, the Assault is paper and the tactical is scissors in my opinion. All the classes can kill each other, they generally have set in weaknesses though as to not have one class dominating.
So I am really really enjoying this game, and I imagine I will be for a long time to come. My handle on Xbox is Caldera02 so send me an invite if you wanna game.
