The easiest mode is 'HARD'!
BUTCHER is a fast-paced 2D shooter and a blood-soaked love letter to the cult classics of the genre. As a cyborg programmed to eradicate the last remains of humanity, your sole purpose is to well... annihilate anything that moves.
So grab your weapon of choice (from chainsaw, through shotgun, to grenade launcher) and kill your way through underground hideouts, post-apocalyptic cities, jungles and more. And if you're feeling creative, there are plenty other ways of ending your enemies' misery - hooks, lava pits, saws... no death will ever be the same.
If kicking corpses into a lava pit and adorning walls with blood is your idea of a good time, BUTCHER is THE game for you.
