It's a key from Indie Gala 4!

These too: Disciples II: Gallean's Return and Alien Shooter

Was browsing my old Indie Gala purchases and I find 3 games from my Indie Gala 4 purchase that I haven't redeemed yet.

Back then individual keys from bundles weren't allowed on this site yet I really didn't want these 3 games, so I left 'em alone and forgot about it... But now that individual keys are allowed, might as well give 'em here; someone might actually enjoy these games.
