Trying to top Arvie's hard score on the first map reminded me about focusing on wave timings. (Which you have to do to beat the first game and a lot of its DLC, but I had forgotten like I forgot about checkpoints.) I kept coming up like a thousand short, then I popped a green inferno in the middle of the map and that extra fire damage over time seemed to take care of the little things I needed. Reminded me why I use to use random lasers a lot in the first game.
Still only edged ya out by 500 though because of some bad overplacement early on.
Also that first map with missiles available is kinda hilarious.
