Lacking funds and need your gaming fix? Got you covered! Company of Heroes 2 is currently free to grab on the Humble Store.
Developed by Relic Entertainment and originally released for Windows back in 2013, it was later ported by Feral Interactive to Linux in August of 2015. It has a single-player campaign, as well as multiplayer versus the AI and Linux/Mac online multiplayer.
If you're unfamiliar, here's the Linux launch trailer:
I've personally put many hours into the game and I do enjoy it, so hopefully more of you will be able to get involved now too.
If you enjoy it, be sure to check out one of the DLCs in future to support Feral Interactive so they can continue to port Linux games. Most of all, just enjoy a good free game! Grab it free right here.
Ps. As noted in our comments, be sure to redeem the key by December 30th.
