Ridiculous story when you consider the science. But I guess it can be accepted as a game. By the way, in this other timeline, is cheese used as a currency?
5/5
This game is very fun and addicting. A great combination between SAS:ZA and BTD. It is also fairly challenging, which forces you to decide between different strategies on different levels. The only problem I have with it is that it will occasionally freeze at certain points while playing. (this happened a few times in dead warehouse, but I eventually got through it. I have now played shop till you drop twice, and it has frozen at the same point both times.) I'm not sure if this happens to anybody else, but it can take the fun out of the game greatly. Ultimately, I give the game 5/5. My rating isn't hindered by the freezing problem due to the enjoyment I get out of playing this.
You should be able to kill guards while they're in scout mode, but to make it fair, the others get alarmed right away. The target should also be more defensive, like running away when he sees you.
If anyone is having trouble with covert pops, the secret is to activate the fully-upgraded buccaneer specialty building and group all of your towers in the buccaneers' radii.
