Not free, but the best sale I’ve seen for Xcom 2. Unknown how long it will last. (while I still love Xcom Enemy Within, I’ve been meaning to get 2 when the “stars are right” and Great Cthulhu sends me an awesome sale.) Ph'nglui mglw'nafh Cthulhu Steam wgah'nagl fhtagn.
Honestly if you try vanilla X-com 2 after having the straw hat version of the complete game it feels really lacking. so the WoTC dlc becomes essential after a bit. so getting everything for 10 USD is a good deal all things considered. the long war mod improves the game alot though.
Epic store has released the base game for free from today until next thursday. there is also a steep discount on the DLC bundle for the game for 9 USD, so if you are interested in getting just the base game you can get it free of charge and if you want the entire thing you can get it for cheap too.
