Skeletal Avenger is now available in Early Access on Steam. What is it? It's another action rogue-lite similar to Fate but also offers co-operative play right out of the box(or download). You can currently get it for 10% off through May 5th, which is $15.29US. Here's some juice:

Current Features at Early Access Launch

• Decapitate yourself to do special attacks: Your hat determines the effect
• Nearly a dozen enemies to fight in two biomes: Dungeon and Sewers.
• Procedural roguelite levels in reverse: Ascend from the depths to avenge!
• Equip your skeleton with increasingly powerful gear
• Buy upgrades increasing your might
• Single player and simple 2-4 player local co-op

I like seeing environmental traps in the trailers for these things. If you're going to have real time, lasers, fireballs, etc. are a must.
