I'm stumped. Why does the game suddenly end for no reason on "stop the rush" type levels even though no enemy has reached even the middle of the screen yet?
That has to be the easiest medium challenge on the site. I'm not sure any of my turrets even took a hit. I give the game overall a 3.5/5, rounded up to 4. Bug on 5th campaign, stage 9, where my purchases and upgrades were resetting when I died, but my money wasn't, so eventually I ran out of money to even repair and had to restart the campaign.
I got the badge, and thank God its over, because this game is awful. Bad music, really bad controls, and survival is based almost entirely on random luck. Did you find a few randomly placed circles before they became an impenetrable wall? Did they randomly drop something good? No? Well, you lose then. 1/5, because I can't give anything lower.
