New Left 4 Dead 2 details emerge from the swamp

In this preview of Left 4 Dead 2, some brand new details about the game have been revealed, including some new infected types and more details about the Swamp level. First of all, the level-specific infected, known as ‘common-uncommons’, for the swamp have been revealed. We already knew about the ones with fire-proof suits on, but the swamp level has ‘mud men’, who run quickly on all fours through the swamp, making them difficult to spot.

A new special infected is the ‘Spitter’, who provides a more long-range option for the infected. He spits out an attack (unspecified at this point, probably gob) that damages those who stand in it. The attck isn#t fantastically powerful but can hinder a team who stay in the area of effect too long. Finally, the preview mentions adrenaline and ammo packs (which replace pills and first aid kits). The adrenaline packs allow you to run past zombies without them slowing you down, as well as removing restrictions on your melee attack. Sounds good to me, although removing health packs seems a little odd. I trust Valve, though. They know what they’re doing.
