EDIT: Sorry for being salty, but that isn't exactly the way to make someone enjoy a game. Hope you consider adding warnings or something when the difficulty is going to take a sudden massive spike in one wave.
Original post: Stained Mountain, Wave 41. WTF.
4 hours down the drain because you decided to do a 'gotcha' moment. Two massive mechs come and wreck my base in less than a minute because my 40-50 lightning cannons that were absolutely killing it for the past 40 waves acted like they weren't even there.
F this. Not enjoyable if you're not even going to give a "Hey, you're gonna get absolutely wrecked next wave if you don't have a million guns and some artillery or something". Nope, we will just let you fall into a false sense of security with weak wave after weak wave and then pull that bullshit. WTH.
And why in the hell can't you have saves within a mission? I could have at least loaded from an earlier save, but nope. 4 hours gone. Yay, that was fun.
It'd be nice to save maps for that reason, but also because it'd be nice to go back and look at factories I really liked and explore them more. Damn shame I have to give up all my work when I want to leave to the next map.
Ugh, so frustrated.
