That Humble Bundle with Trine 2: Complete Story, Mark of the Ninja, Eets Munchies, and Brutal Legend has gotten even better with the inclusion of four new titles.
Customers who pay more than the average (still under $4.75, at the time of writing) will also get Rocketbirds: Hardboiled Chicken, A Virus Named TOM, Bastion, and Limbo. Plus FTL and Fez, since those were the original pay-more-than-the-average bonuses. Go buy this thing already!
We've talked your ear off about Limbo and Bastion, so I'll save it. I can't personally speak to Rocketbirds, but A Virus Named TOM is a fun, cute, under-appreciated gem of a puzzler.
