I have unlocked numerous achievements and they display in the game but I haven't unlocked any Steam achievements. Is this a known bug? I haven't seen anybody else talking about it.

How can you get this? Only flame turrets but the game throws a ton of flying units you can't kill with anything else than the machinegun turrets??? The drone doesn't let me target any flying units when they are next to the base, so only way to deal damage to them is by the airstrike, and fully upgraded airstrike is not enough to kill even one of them....

Game soft locks at end of any mission in which I get an achievement, the game is still running but the mission does not end after all waves are killed, and no menu is accessible, only aft-f4 can escape the game, this sometimes leads to losing the mission plus achievement....

Is it actually possible,? I got to wave 30/30 and just got annihilated

... on Survival? is that good for a first try?
