The objective of this game is to destroy enemy tanks while you avoid getting hit and protecting as many A-Bomb sites as possible (up to 25). You destroy enemy tanks by firing shells. Enemies arrive at the site one at the time (Level dependant interval). Enemies first move randomly and then they try to get directly to your depot to destroy your Bombs. There are 25 different A-Bomb sites. You advance to the next site upon destroying all enemies presented, other enemies abort the attack and you get a bonus. There is a maximum of 9 enemy Tanks at each site.
