Were people still playing the tower defense minigame? I wasn't paying attention but i did notice people saying it was hard
beat it first try, just abuse the fact that the slowdown tower freezes anything hit while it's midair and stagger them to stag multiple cars on top of one another, then reap the rewards by only using the railgun (which hits multiple vehicles in one beam, place it down a straightaway) and spamming aoe
they never made it past the first curve
