Zombies! (Kind of)
The second day of the Steam Summer Sale sort of has a zombie theme (if you don't pay attention to all the games that have nothing to do with zombies). Let's jump right in like we're on the high dive and we're totally not scared but everybody's watching so we have to do it.
The Flash Sales for the next eight hours or so are Spore ($7.49), Pixel Piracy ($7.49), Mount & Blade: Warband ($3.99), and Dungeon Defenders ($3.74). Additionally, "Underrated Shooters" won the Community Choice, meaning the following are discounted: Rage ($4.99), Call of Juarez: Gunslinger ($3.74), Bulletstorm ($4.99), and Orion: Dino Horde ($1.49).
