They need to stop doing this crap, really. Give the players more details so we can tell you if its a good idea, because what they've been caning out lately has been lackluster at best and not something players can invest in longer than your typical 4v4/8v8 player head bash session.

Anyways my speculation is they're going for a PvP Strategy Mode. The crystals could be resources that your players have to gather for points (hoping we can use them to get special weapons or support mechanics). I see a pillar with an odd cross on it, so I'm guessing a checkpoint system or a base of some sort that players have to capture. The area looks genuinely big, there's also a bridge in the second picture on the far left, maybe that's where our base spawn point is?

I dunno. With how they are dealing with content as of late I'm going to leave some more low expectations as I did with Feast which was also lacking in diversity. :/
