Made a massive mistake. Used Kred to buy gems. Then realised that I had better things to do with my life than waiting for the game to connect. So much potential...
Is it me, or does the computer seem to have some really unfair abilities later on (like 20% chance to evade damage). I guess it's one way to increase difficultly but feels cheap to me.
Just did 3000m on Endless Mode before I got bored. My tip is to make sure you have all the upgrades first. Perks I used were: Armor, Nano Bots, MRE Pack and Fireproof Spray. Used Air Support (although I suspect this may not matter too much) and Missile Launcher. Try to recruit Rocketeers and Marksmen only. I found that my recruits were nigh impossible to kill, and you really have to concentrate on avoiding the Instant Kill things (like running into buildings). Hope this helps someone!
Fun, but would be better if you could turn off upgrades. Some of the missions are impossible without it (like the one where the leader. has to run a certain distance by himself).
