2v2 Mode Announced
Mix and Match Weapons
Elemental Type System
New Character: Min Min
For 2v2 it definitely looks like it's using a "target switch" button to change opponent lock-on, plus it looks like there's items as well as there was an area-based team healing drop at the end of the gif. That wire between the two characters is probably just identifying your team mate and relative position.
EDIT: That healing item might be for everyone vs activating it for your own team and you have to push the opponent out of the healing zone.
