After 2 years its finnaly over with a lot off cheating and other tricks i did,it its too dam hard to play alone needs a loot o luck

If you are playing Veteran and it starts to being hard and each time you lose your gun power it becomes harder, try this.. There is the save location: C:\Program Files (x86)\Steam\userdata\154330417\377460\remote\steamcloud\CI3 After every succesful wave, quit the game, ALT+F4. Then copy and paste the folder in CI3 location above. Then, open the game and continue. If you fail, just quit the game and replace your actual save folder with you just copied....

And second question: how to get the "Distinguished Green Greed Cross" achievement? what do i have to do? Help

Does anyone even play multiplayer anymore?

I wish I could refund 3, 4 and 5 but like I did with 2 but oh well, too late. For anyone who wants to buy this one: DON'T. It will make you rage SO MUCH you will surely break something in your room.
