If you missed the Indiegogo campaign, you can back RIOT here:

For $10 you will get the game for PC, Mac, Linux and Android once released.
(Depending on the App Store restrictions and workarounds, you may or may not get the iOS version as well)
RIOT is in active development, but still at an early stage. We aim to reach the beta in the next months.

For $20 you will gain access to the closed beta (once it starts). Try the game before anybody else!
