Tip: Don't use any tanks on Mission 9. When they explode, you lose far too much morale. What worked for me was deploying lots of Assault Teams (best for entrenched and tanks), and using every Fire Support as it appeared. Past that, it's luck. Sometimes the Anti-Tank is right on target at takes out their tanks at once... Sometimes it doesn't, which makes it much more difficult to take out their tank. Difficult, not impossible.
I enjoyed this game far more than I expected to. Shooters aren't generally my genre of choice, so I figured I'd play just as long as it took to get the Badge of the Day, then quit. But then I kept playing. I found a gun combo that worked for me (Remington and M4). I figured out that the people with skill in searching were not the best ones to put in a search party--people with melee skill are less likely to be discovered and more likely to survive. I went from 0 morale to 100 at the end of the game because of this discovery.
I don't tend to choose games like this, but I really started to enjoy it! Excited with every lucky shot, strategic with mine placement... Bradley Fernandez the cat was certainly an asset to my team.
Accidentally reloading was the only real annoyance, especially since it generally happened when I really needed to be shooting. The old lady zombies also were the bane of my existence. They can eat bullets.
5 stars for a solid and surprisingly fun game.
I've seen worse controls for picross/nonogram/griddler type games. But I've definitely seen better. It's far too touchy on getting things "wrong" (sliding my mouse too fast to fill in a line got me a penalty, even though the offending pixel was already marked blank), and sliding to mark extra blank spaces should not erase those that are already there.
