DAMN
ive actually in the making of a game similar to this
basically its a survival game, the ghosts from pacman are the main 'zombies', theres also the space invaders (which look identical to the ones posted above), which would attack the player, the landscape is made up of tetris blocks, objects such as fans (too reach higher places) are dropped in crates (dropbox). after soo long the enemy gets a deathstreak and snake enters destroying terrain, and causing a chain reaction of similar coloured tetris block
the player would also have several guns which would interact with the terrain aswell
they only reason ive stopped working on it was, it was getting difficult to make the terrain a bit more attractive, to dull and monotonous
anyway back on subject, Brillant video
