I got it with Sor2 route, used Sor2 Shiva and Max agressive CPU partner. The other two continues CPU chose Skate; I used one continute and used Sor2 Shiva again. Oh, and five lives of course.
Damage was off between players, so what helped tremendously was beating up enemies from both sides and protecting Max since many enemies strike him during his combo. Unlocked Ending 8 as well. This was my only playthrough w/ the CPU partner and I must say AI for the partner is soo much smarter and helpful than in V.4. A totally vast improvement.
So now I've unlocked all endings, characters, cheats and extras. I will try my hand at the events mode, suvival and boss rush modes (I really suck with survival/boss rush
). But personally, I love playing through the main campaign; it is great fun!!! Cutscenes, awesome remixes, stage routes, upgraded stages and the character roster are what appeal to me the most. Will also have to try with some cheats, like light saber and exploding enemies.
