Apocalypse Greg, Vol 4, 5

APOCALYPSE GREG—(Light Novel Vol 4, 5) "No walls can contain my hatred for group projects." When our reluctant hero Greg Michaels discovers a mysterious black-clad figure capable of slaughtering entire settlements, he realizes even the apocalypse has corporate middle management. Tracking this "Cleanser" through the scorching Arizona desert, Greg discovers non-System survivors hiding in the Phoenix Zoo and ancient cliff dwellings, desperately trying to survive both zombies and these invincible assassins. But the trail leads to something even more disturbing, Las Vegas, completely walled off from the world, where androids hunt both zombies and humans. As he infiltrates the Strip, Greg uncovers the dark secret beneath the Black Tower, a portal to the zombie realm itself. With nothing but his trusty sword and a talking android head, Greg does what any reasonable introvert would do: jumps straight into hell to fight the source of the apocalypse. Because at Level 99, he's done carrying this team project called humanity. The only thing worse than an office party? A three-phase boss fight against the Lord of the Depths for the fate of the world. At least there's no small talk.
