I lost the first four times, but the more I play the easier it gets as now I win about 3 out of every 4, and the ones I lose are because of team mates not working together. I can even beat the blue sparkly marsh mellow boss now. 
To everyone playing this gamemode, please stop just running to the truck and entering it as quickly as possible. You only get the Points of players who entered the truck and once someone enters it theres a 30 sec timer before the game ends.
So please wait for teammates at the truck,
its really frustrating searching for tokens half an hour and putting soo much efford in not loosing them and than one stupid teammate enters the truck and leaves and you stay behind and nobody gets the 120 points you carry
