You gotta listen to Sonic in situations like this. Just rush and leave your teammates behind. The reason I had to rush this map was because it barely gave out any items and there were 2 tanks that spawn behind you in the first chapter. Rushing is a strategy that doesn't really work because of blockades or events that force you to stop but this map didn't have that. So, it's a viable strategy.
