Pretty cool
One problem is the amount of luck involved, especially on shotgun missions. There's the one where you're not allowed to hit a single gringo, which you have next to no control over. And then there's the one where you have to shoot down all the drones in 4 shots. Not only do your shots fire in random directions but the drones are in random places.
Another problem is grinding. Once you've got all the stars, it should just automatically unlock all the glossary pages. I'd like to read them but I don't want to have to just sit there shooting locusts until I have enough money to buy all the scatter upgrades. And I'm certainly not gonna sit around shooting stuff until I get all the achievements.
The art is certainly good. I like the all-female military squad. Kind of reminds me of rtil's Freetown.
