Here's a little treat for Valve fans: Capybara Games is adding three characters to Super Time Force Ultra, which will be playable on Steam next week.
The characters are Saxton Hale and Pyro from Team Fortress 2 and Left 4 Dead's Zoey.
All three Valve characters, along with 50 new Helladeck challenge levels and the new Ultra Force power mode, will be made available in STFU (I love that acronym!) which releases on August 25. It will run you $14.99.
