Regular Show: Nightmare - Athon

Regular Show: Nightmare - Athon drops Mordecai and Rigby into a horror movie night that goes completely wrong. A zombie flick is running in the theater, the seats are full, and the screen suddenly turns into a real portal. Walking dead pour into the aisle, and the crowd in front of the screen turns into easy targets. The guys stay in the hall instead of running, and the whole place turns into a defense zone. Mordecai stays in the back, protected by the audience rows, and launches heavy cannonballs at incoming zombies. Rigby moves along the front of the screen with a basic melee weapon and stops anything that gets too close. The whole match plays out in that single movie theater, so all danger comes straight from the screen side.

How to play?

Smack zombies with Rigby to clear the closest lane, then let Mordecai finish groups with his limited nukes. The game gives 100 cannonball shots total, while Rigby's stick attacks never run out. Those melee hits also collect power-ups that appear on the floor, so keeping Rigby active keeps the upgrades flowing. Catch bonuses fast to refill or swap Mordecai's ammo, then pull back and let him blast packed lines of undead. Breaks between runs reset Rigby's position but do not reset the danger, so plan charges instead of just rushing. If any zombie reaches the seated audience, the round ends immediately. Hold the screen line, protect the moviegoers, and clear the whole wave of zombies to keep this horror marathon going.
