If we learned one thing in the Girl Scouts (don't judge -- you'd join for the Thin Mints too), it was to always be prepared... for the zombie apocalypse. Sure, you have a crossbow, an axe and a stash of high-powered weaponry in the barn out back, but what about the downtime? Yahtzee is fun for two weeks, or until you suspect Grandma of loading the dice, but after that you'll need to find some other entertainment.

The Quadtastic Launch Collection from Radiangames offers four new titles for PC and Mac, at a $10 pre-order price. The Collection drops Jan. 24 and will be $12 from then on out -- it includes Inferno+, Ballistic, Slydris and Fireball, all styled in the same techno-pretty tone as Radiangames' previous title, Super Crossfire, which was included in the Indie Royale New Year's Bundle.

Radiangames will donate a sliding percentage of sales to Child's Play and St. Jude's Children's Research Hospital charities, so even if you don't care about the zombie apocalypse, you can care about some kids in need.
