"Zen Wars offers a multitude of weapons for you to destroy your enemy, whether you opt for the inexpensive standard cannon that can destroy a wall piece per shot, or one of the more exotic weapons such as the laser cannon, which destroys everything along its path, including your own walls! Whatever your style, Zen Wars has the weapons for you. Don’t place too many cannons though, or you might just run out of space for your repairs." Source: The Game Website.
