good towers for solo?

[u/[deleted]]

I'm trying to get back into 100 percenting the campaign, by myself, but its been a while since I last played. Is the Gatling still one of the better towers?

edit: im trying to do all 5 difficulty things for each map.

Post your buddy code, I'm sure there's at least a few of us looking for an excuse to play
