Area burst towers are very OP. One reason: the damage is almost immediate while the bullets of the other towers have to cross the screen. And the bullets are quite slow.
My plan: Don't upgrade, buy the T2 first and second. Goal is the two UAV trucks - so save for T4 bomber, T5 boss. Upgrade in top-down order until you unlock T4 bad boy. Tactics: launch 2 UAVs. Fire rail gun down road, strafe air and return to road for rail gun again. Use grenades on big choppers.
Worst Feature: Collision box is your/zombies entire body, so you can't run close past them. That means the street is actually really narrow and passing between zombies is impossible = control skill is useless.
Just so you know - This is Tuesday's BotD and I already have the other six badges for this week. (and all the badges for version 1) I will not bother with getting this one. :(
I also go the black screen. Inspection had this error: undefined:1 Uncaught (in promise) DOMException: The play() request was interrupted by a call to pause().
Note: Has a BubbleBox banner, but I tried it there and the black screen came with a screen of errors! :P
*** Did you finish with a single color but get a "Failed"? I think if you paint with the same color twice in a row it is a fail. You must switch colors between clicks.
A feature request: Have the engines turn off if your ship is upside down. When I hit something and tumble, if I hold the down key while trying to recover the buffer gets full a its impossible to control.
Sparta, No Shots Fired: For those who feel that guns are too violent - buy and max out a Flame Thrower and 3 fans. BBQ! Lazy? Use a maxed Flamer Joe (centered) and 2 Fans with a 400 wall and repairmen.
@aquatorrent and others playing the campaign: You get more money for killing them early, and almost nothing once they reach your wall. So either be a perfect shot or alternate killing the lead guy with one that just appeared. I really don't know - the reload delay always puts me behind so I get less money, then I don't have enough firepower for the next wave.
