It took a few months, but Borderlands 3 has finally hit Steam for those who were waiting for it on Valve's storefront. The game is currently half off so you can pick it up for a measly $30 instead of the usual $60.
What might be a first is the ability to not only play with your friends on Steam but to play with those on Epic as well. This is a great addition as now you're not going to be separated from friends who own the game on one store or the other.
Check out Russell's review of the game where he gives it a solid grade.
