This is the story of the Battle Cow in Haywire Valley who set out to save her friends and farmer from intruders who have taken over her beloved farm! The game story is all about how the Battle Cow fights for the rights of her friends, who are trapped in their own farm by a gang of enemy animals led by their Boss; Rhino.
The game features two different modes: the Pen Mode and Farm Mode. In Farm Mode, the player can freely explore and roam the Haywire Valley landscape to collect coins which are going to help in the Pen Mode. Coins are used for upgrading weapons and buying ammo.
Pen Mode is available by visiting designated pens spread around the Haywire Valley. In Pen Mode, which corresponds to a new level in the game, players are challenged to fight off enemies in order to free the captured friends. Every Pen features a unique environment and enemies. Having managed to take back a pen from the intruders, players are challenged with a set of tasks to complete before being able to proceed to the next level.
There are 20 Pens to be won before the player is challenged with a last and final battle of Haywire Valley – an almost impossible task! But do not fear, we have a Battle Cow!
