Nightmare-athon

Nightmare-athon is the most recent Regular Show game. It focuses on Mordecai and Rigby trying to fend off zombies who want to get the audience members during a screening of Zombocalypse 3D.

Gameplay
The player takes control of Mordecai and Rigby to fend off the zombies. The mouse is used to control the duo's vertical movement, and left clicking will have Mordecai throw a weapon at the zombies, to the right of his current position. Rigby acts as a special attack, as there is a meter that fills up gradually, when it is about two-thirds full, pressing Spacebar will make Rigby dash out to the right and then back to Mordecai, whacking zombies and collecting power-ups that come in contact with him. The mouse can be used to control Rigby's vertical movement while dashing. If the meter is filled up 100% when the dash is used, Rigby will have enough energy to dash out and back twice instead of once. The game is played in rounds, with each round lasting 1 minute. When time runs out, any remaining zombies on-screen must be destroyed to clear the round. At the end of a round, the audience cheers, and Mordecai or Rigby will usually say a catchphrase of theirs.

Power-ups
The following is a list of power-ups found in the game. Besides the Bowling Ball, they give more points than normal when used, and combos score even higher.


 * Bowling Ball (99 ammo, resets after the Discus or Bombs are used): The main weapon that you have from the start. Mordecai throws it to attack the zombies, but its range is not too good.
 * Discus (10 ammo): The most common power-up, this item flies straight out when thrown, immediately killing zombies in its path by decapitating them.
 * Bomb (10 ammo): Hits zombies in its path like the Bowling Ball, but when it lands, any zombie in the blast radius will take damage.
 * Javelin: Used by Rigby. Instead of using the pole, he will use this power-up when collected. It lasts until the end of the round. Unlike the pole, it immediately kills zombies by spearing their heads, making Rigby's dash stronger. This is the best weapon for combos.
 * Golf Cart: When collected, Skips will drive the Golf Cart back and forth across the screen for a few seconds, killing any zombies who cross its path.

Trivia

 * This is the only Regular Show game so far in which Mordecai and Rigby talk during the game, most of what they say are catchphrases of theirs.
 * The "zombie killing" focus of the game is from the episode Grave Sights. It even mentions the movie used in the episode, Zombocalypse 3D.
 * The game was released in October, due to it being close to Halloween.
