The first game from fledgling indie studio Borderline Inappropriate Game Studios, Undead Blackout is a fast-paced, action filled, top-down zombie shooter that can be enjoyed alone or with a friend. If Super Smash TV had a baby with Left4Dead then Undead Blackout would be the tiny, zombie offspring.
Escape to safety in Arcade mode or try your hand at Survival if you don't fancy some old-school level to level progression. Survival mode simply sees you facing off against zombies for as long as you can and racking up the most amount of points possible before inevitably meeting your demise.
Arcade mode can be played in split-screen Co-Op while Survival has both Co-Op and Versus modes, Versus mode simply being a battle for the highest score or you could ignore the scores and just try and kill each other while avoiding the undead.
With gameplay that is different every time thanks to random elements such as gun and ammo placement, key locations and zombie behaviour, you will find there is an immense amount of replayability across all of the game modes.
