The death effects are also worthy of note. When zombies and enemy marines sustain massive damage, such as from a close range shotgun blast, they simply disintegrate into a cloud of debris and a skeleton which blows apart and crumbles to dust in a split second. This is an incredible effect which is hard to get tired of. If you've seen the move Blade you'll know what to expect. Demonic creatures fall to the ground when killed, before rapidly burning away to ashes.

Early on in the game, it's easy to feel that your weapons lack punch. The shotgun has a pleasing oomph, but is pathetically ineffective outside a few metres away, while the machine gun and pistol lack firepower. At least ammo is plentiful. Once you find the chain and plasma guns, you'll feel a lot more dangerous, and the game ratchets up the frequency and scale of the fire fights accordingly.

All the weapons in the game have a single style of attack. No secondary firing modes here. This is a good thing, as it keeps the focus firmly on the game play, not the tools. This is not to say the weapons are boring though.
