Battle Species is a fast-paced game where animal characters are fighting against each other in a pirate theme. Playful game mechanics, destroyable terrain and clear graphics make the gaming experience interesting. Your job is to control a mole on a catapult and try to eliminate a bunch of pirate monkeys that have conquered your castles. Monkeys will use their cannons and battle ships to make it as hard as possible for you as a player. Luckily you will constantly receive some help from above, in form of air drops containing special ammunition to be thrown at the monkeys. Air drops can also carry medikits and special kind of shields to protect you.
The single player campaign includes fifteen different levels which can be played on three difficulty levels. Each level features a randomly generated terrain, which will be different every time you play. Levels do not have any time limits for completing them, but destructing terrain and slowly rising tide make the job harder as time passes.
