Big Warhammer fan, so this kills me.
Space Marine multiplayer can bite me. I still play it. I'm still freaking in love with it. But this is such a lag fest that I can't even beginning to comprehend. And it's one of those games that favors the laggers. I'm safe behind a wall and he's shooting me with a bolt pistol? Still killed. That lagging Raptor is swinging at a stairwell and I'm about ten game feet away? still killed. I finally lined up the perfect headshot and am about to hit the mouse 1... "Migrating to a New Host"... Prey moved away in that time.
The worst part is, they have the makings of a great multiplayer here. Have the armor pieces mean something than just visual dressing, like the Spiked Shoulder pad giving more damage when ramming, or Battle Damaged giving you weaker armor but it has an Auspex built into it. Add that along with perks, and with the sheer number of armor, you'd have no two players playing the same.
There's so much lore too. Have more Challenges where you unlock other chapters, and chapter specific traits. you unlock the Emperor's Children, and instead of a melta gun, you get sonic blasters. wouldn't just be a skin either. Charge it up and kill one person and dizzy others in a small radius. Unlock Space Wolves and get frost blades, the strongest chain weapons in the game. Iron Hands are faster because of their extensive bionics (I know someone will think of the White Scars, but remember their quickness comes from their bikes) and The Night Lords can become invisible in the shadows. There's so much lore that could have lended to such a massively satisfying and ever changing multiplayer experience.
Instead (while I am addicted), it feels like THQ just read a few weapons, made a few classes, and made some skins instead of making true Space Marines and Traitor Legions.
If any of you from THQ are miraculously reading this, Make the sequel to Space Marines a single player and co-op, and come out with a fully realized Chapters and Renegade Chapters. Please!
