Now you can escalate that race even further with War of the Chosen Tank Mod. The mod adds massive tanks which serve as their own class with a full upgrade tree that unlocks special abilities.

Since XCOM and XCOM 2 cemented themselves as the definitive PC strategy games of the 2010s, the Long War mods likewise became the definitive enhancements for both games.

As Dominic Tarason points out on Twitter, this is the biggest mod for XCOM 2, as anyone who's played the original Long War or Long War 2 mods can confirm.
