The upcoming closed beta for Desperados 3 has now opened for registrations, but you'll need to be lucky to get involved, as developer Mimimi are limiting the number of places to just 500.

The game is a stealth puzzler similar to previous games by the company like Shadow Tactics: Blades of Shogun. You'll need to control several characters in real team in order to complete various objectives, as you can see from the trailer below.

If you want to be considered, you'll need to fill out this online application form, and you'll be bound by an NDA too, so if you do get invited, you'll need to keep it to yourself.

The game is due to come out at some point this year, but there's no release date as of yet.
