Typing of the Dead: Overkill is half off right now in Steam's Daily Deal, which actually runs for two days, through 1PM ET on Wednesday. Typing of the Dead: Overkill snuck up on everyone in October, when it hit Steam from publisher Sega.
Since that launch, Overkill has received a Shakespeare DLC pack, a free Football Manager DLC pack and a brand new, $3 pack called "Filth" that replaces all of the text with innuendo, including lines such as "Man-meat," "Furious penis," and "Always were a cunning linguist." Classic literature, innuendo and soccer. Oh, and zombies. Sounds like a good week.
