[PC] FREE Steam Key - Pixel Puzzles: Undeadz (73% Positive; Trading Cards) - Indiegala

Another freebie from Indiegala. This is actually a pretty good game if you enjoy puzzling while shooting zombies. This has also been free before, so if you missed it here is another chance to grab it.
Also has trading cards which can be sold or used to craft badges to increase your Steam level.

Note: Fighting the zombies while puzzling (Zombiemode) can be turned off so you can just play this as a normal puzzle game with a zombie theme.
