If you have any custom battle, with tanks, you are guaranteed to lose. The enemy will spawn tanks AND infantry, at the same exact time, and will dish out tanks as fast as MGs. Because SOMEONE thought it would be a great mechanic, to allow the ONLY ENEMY IN THE GAME TO DEFY IN-GAME LIMITS. ESPECIALLY ON EASY DIFFICULTY.
Doing my top comment strategy got me more MP by 3000 Body Count in 2 days than me upgrading at any chance by 9500 Body Count in a month. Please, do not like this comment, let my Strategy live on.
Thumbs up if you agree. Add a car sytem (build, find ect.) make it cost a gas can every 10 squares and make it have a chance to need a part (wheel, engin ect.) every square. (0% no danger 10% medium danger and 20% large danger) Hope this gives you ideas>
