Borderlands 2 & Borderlands The Pre-Sequel have been updated with some pretty beefy updates, and they include some little Linux fixes too.
For Linux gamers, you can now set extra mouse buttons to do things, which is apparently a big thing (I never use mine).
You can find the Borderlands 2 changelog here, and the TPS changelog here.
I think it's fantastic Gearbox & Aspyr are still updating Borderlands 2, and I'm sure TPS updates are equally as welcome.
Sometime, I really will finish Borderlands 2, as it's such a good bit of fun. The random weapons are just delightful, and I'm so very happy Aspyr Media delivered it for us.
