Operation Supply Drop is a charity that we've been working with for years, to bring games to active-duty service members and veterans.
This weekend, they're doing a tournament for Khet 2.0 on Steam! Head over to their Twitch channel for more info:

There are rumors of prizes for the winners... best of luck! Support a good cause, slay thine enemies in the tournament, and make me proud! :D
