1 bunker 1 turret at start then place bunkers in every corner and upgrade them. sell turret at air level and build the flak then build another flak farther back when you can afford. continue placing bunkers and upgrading win I only played first 10 or so though
Pff. Whenever I want a challenge, I just program a game which solely uses prime numbers as its variable values. (So any variable in the game at any given point in time always contains a prime number) NOW THAT'S HARD
That's not so hard... Now if you were programming a math library in C with that method... :D Please no one attempt that...
