It's been almost a year since we heard about Bunch Of Heroes. It's a top-down cooperative zombie shooter, and it's coming out on the 21st Sept via Steam and Gamers Gate. There's also a new trailer to celebrate this, which you can see below.
It's looking pretty damned cute. Of course, the smaller-scale your project, the more of a risk it is to want four people to make time to play it at the same time. I look forward to finding out if it's good enough to warrant such attention.
