Good design that you control EVERY character on your side, and there are no NPCs that get in your way, inconvenience you, or that you even have to escort. Shame there's no long-term development.
@Gman6817: To use a spell, click and drag the spell from your inventory onto an opponent that you are currently engaged with (or, in the case of a healing spell, drag it onto yourself).
Alright, two problems: Insta-Kill Grenades (I can work around it somewhat but it's really dickish to have to have the health upgrade to survive an attack) & turn-ending after the enemies' turn, not yours (this is a problem because enemies can take cover outside my range and then move into the area I have to defend, causing me to insta-lose).
Keeps bugging out so my mouse-clicks don't do anything. After the first level is complete I click the continue button and a turret lights up but nothing else happens. : /
Bug: on the Rogue skill-tree, a mark indicating a prerequisite skill is below Poisoned Dagger, despite there being nothing below it. Also, Toxic Blade, despite mentioning a dagger in the info text, does not contain the italicized words, "Requires an equipped dagger!"
My biggest complaint is that the beginning units (cheap and fast to produce) end up leveling up before the more expensive and slow units, so when you want to level up the later units it gets really tedious because they're actually much worse than the early units at the time.
The bosses are just awful! Here we are having fun shooting zombies and getting better at things, then they suddenly jump out and can tank hundreds of bullets and even instant-kill us!? Buzz kill!
I liked this, but I'm hitting a confusing difficulty curve... I had barely been hit then suddenly I died 3 times in quick succession... First, a horde of zombies with guns massed against a wall which only broke when I got near. Second, I was unable to move and dogs mass-attacked the generator. Third, a werewolf thing hit me lunged at me while I was in a fortified position (from an angle he shouldn't have been at anyway) and then killed me on the second swing...
