The Chainsword, Power Axe and Thunder Hammer are each handy, hefty melee weapons Titus can -- or, has to, really -- use to aid him during bigger battles. Sometimes a Bolter rifle just can't take down a swarm of green-skinned orks in the same way a humming, rumbling chainsaw-sword or electrified sledgehammer can. Cutting down enemies is essential not only to surviving, but to what makes Space Marine's combat as distinct as it is. This game is absolutely not a shooter. It just so happens that guns are present, but expect to charge into a terrifying mob more often than hanging back and taking pot-shots from behind a hunk of rock.
