I'm pretty sure these new supplies are a prank, but they'd be cool to see in the game.

I think some kind of competetive parkour mode would be fun. It could work something like this: There is a point somewhere hard to reach (on a roof or something similar), then 2 teams compete to get one of their members to the point before the other team does. Teams would have to balance efforts between doing the parkour, and sabotaging the other team (by destroying them). I am aware that this mode isn't for people not into parkour, but I would really like to see it.

Maybe a gun that has high damage and okay rate of fire, but has bullets that travel slowly through the air, so that people can dodge them.

I'd like some sort of battering ram, which does damage based on how fast you crash into the enemy. This would give an incentive to do parkour in regular battles (for instance, people might try to jump off buildings and land on enemies to do serious damage). I'm not sure whether this would be a turret, or maybe there could be a new hull that does this?
