Insidia is the latest indie game bolstering the renaissance of the glorious tactical turn-based genre. Developed by Bad Seed, it’s focused on PvP battles that blend elements of X-COM and League of Legends.

The game is about to launch as a free-to-play title on Steam Early Access, but we’ve got 500 codes that will let you immediately into the beta. You may redeem these codes on Steam.
