Most people say it’s a multiplayer game, a few say the missions solo are tedious. But we all know it’s actually great 
I had a blast playing all three Borderlands and their dlcs, and Battleborn just feels fresh. All those different characters and their different play style add a lot to the gameplay and keep things interesting for replaying levels.
I feel like Missions 2 to 7 can be done with any characters on Normal. I haven’t tried 1 or 8 with a melee character yet. Hardcore? not so much. Mission 5 gave me hell. Reyna was not a good option either… I do feel comfortable with Marquis, Ghalt (thanks to the key) and Oscar Mike (not powerful enough for me) but it’s really fun playing melee characters, mostly on defense missions.
I did get a couple of gold medals, but mission 3 is the only one I still have bronze.
I need to complete :
- Hardcore mission 8 (I have to figure out how not to die by falling)
- Advance 4,6,7,8
- Silver or higher on mission 3
