I never could figure out how to play Infected. I'd rather a shotgun than a tongue, an AR instead of air, and a nice cold Mollie than smashing through a wall.
Molotov over "I'M THE JUGGANAUT, *****!"? But yeah. Jumping around via the mouse, and shooting a tongue feels... I dunno. Weird with a mouse.
Being the target of every gun in seven city blocks over lighting near unlimited amounts of things on fire? And I'm alright with being the Hunter, but that's only because I naturally like to climb as high as I can in most games.
Hunters rock, but people always fail epicly when using them. You need a boomer on at least 2 others, before jumping at one of the survivers without the goo on them. Only way to do decent damge. Or my favourite: go to a ledge where people cannot go back up as a smoker. Wait until all but 1 have gone over the ledge, and then pull the other back. Then use a boomer to call in more zombies, then kill him. Epic win guaranteed.
