Amplitude Studios has released its challenging roguelike and tower defense hybrid Dungeon of the Endless via Steam Early Access today. The goal is to protect the generator of the team's crashed ship while exploring an ever-expanding dungeon. Each opened door can lead to resources to build defenses or to powerful enemies ready to destroy you and your generator.

For $10 (a 25% discount), your Early Access build will have 3 of the 12 levels (the first level is hard!), along with all the updates up to and including the final release. The team has the full version of Dungeon of the Endless tenatively scheduled for next year.

To make sure it's not just me, I have given a code to one reader who has agreed to report back on the difficulty in the comments below.
