It won't take much to get involved. Revival is promising a digital copy of the game for PC, PS4 or Xbox One if you make a $25 pledge; paying more gets you art, strategy guides, in-game credits and hard copies. There are plans for Mac and Linux versions if the team meets stretch goals, too. You won't get to play until March 2017 if Overload reaches its target, and it's not clear if that will happen. How many gamers need to relive their glory days twice? If you missed out on Underground or want to reward some game industry pioneers, though, you now have your chance.
