Fortix 2 for $0.99 ($0.74 with GalaPoints) @ GalaStore

Linky

I haven't checked their store in a long time but was pleasantly surprised to find Fortix 2 on sale. Granted it's probably not highly desired, I assume there must still be some people like me who've missed the bundles for it and wouldn't mind spending a dollar or less on it.

Also, selling the cards will get you roughly $0.60 in Steam Wallet so well worth it ihmo.

Cheers!
