The first is annihilation, which is a standard team death match, with the winning team being whoever reaches 41 kills first. In competitive multiplayer, there are two different game modes. There are three classes the player can choose from on the side of the Loyalist Space Marines or the traitorous Chaos Space Marines.The player can gain experience in gameplay by getting kills and assists on kills which will allow him to gain levels.There are also challenges associated with different weapons that will unlock perks for weapons or armour pieces to customize a player's Astartes. In addition to the cooperative mode, a player can engage in an 8v8 class-based team competitive mode. The cooperative mode is similar to the typical 'horde' mode found in other action video games where players team up to defeat wave after wave of enemies, but is unavailable at launch, launching instead 30 days after the game itself first becomes available. In Space Marine, there are two multiplayer modes. Purity Seal вЂ“ Awarded to those Astartes who show themselves to be honourable in battle, this authentic poly-resin purity seal with double cloth ribbon and magnetic attachment is a replica of those worn in-game by Titus.Soundtrack вЂ“ A musical score for the game by renowned composers Cris Velasco and Sacha Dikiciyan.Art Book вЂ“ A hardback art book with art from the game provides a behind-the-scenes look at how the universe of Warhammer 40,000 was brought to life, complete with developer introduction.Information Cards вЂ“ A pack of 25 foil-treated collector's cards that provide key information on some of the main characters in the game, complete with gameplay hints.The Collector's Edition of Space Marine includes the following: Plasma Pistol (Mark III Sunfury Pattern)ДЄ main feature of the game is the ability to customize the player's Space Marine Chapter by colour and iconography in multiplayer, thus representing the many different badges and paint schemes available in the actual tabletop game.Many of the iconic weapons used by the Space Marines in the Warhammer 40,000 universe are available to Captain Titus in the game, including: Warp portals conjured by the Traitor Legions allow the Daemons to cross over into realspace. However, the forces of Chaos present a far more serious threat to the Imperium of Man, as they can literally extinguish the life of whole star systems by summoning limitless amounts of daemonic horrors that flourish in the parallel universe known as the Warp.

The Orks are a hulking, green-skinned alien race whose sheer numbers and savage ferocity make them a devastating opponent. The main antagonists the player must fight in the game are the Orks and the forces of Chaos. The game includes a new weapon not featured in the actual table-top game known as the Vengeance Launcher, which can shoot mines that stick to enemies. Titus' starting weapons include a Combat Knife ( Power Sword if the game was preordered through THQ), and a Bolt Pistol, though the player can acquire other weapons ranging from Plasma Guns and Lascannons to the mighty Thunder Hammer. The game features a fury system that, when filled up, allows the player to either slow down time to enhance aiming or perform devastating melee attacks. Titus is accompanied by Sergeant Sidonus and Battle-Brother Leandros, both members of his company's command squad, for most of the game's missions, though in some instances Titus will have to go on solo missions. When the player's health gets low, performing special kill moves called executions can allow Titus to get a portion of his health back.

As a Space Marine, the player is given enhanced regenerative abilities and an Iron Halo containing a regenerative protective Conversion Field emitter. Space Marine does not feature a cover system, like that used in the Gears of War franchise.
