No editing, just shooting: Unlike a classic Box where the fastest editor wins, here it's the one with the best positioning and aim. The Bubble replaces the Wall: In a PvP Box, you place a wall to heal yourself. Here, you deploy your protective bubble. It's your only temporary cover. Movement with the Grappler: Since you can't use ramps to climb, the grappler becomes vital for surprising the opponent in the bunker.
