Jeff (
Joel McHale) and Britta (
Gillian Jacobs) enter the study room arguing. The rest of the study group complains, and Abed (
Danny Pudi) explains that Jeff and Britta's sexual tension is dividing the group. Dean Pelton (
Jim Rash) announces a game of "
Paintball Assassin" with a prize to be determined. Jeff leaves to nap in his car. An hour later, he awakens to a seemingly abandoned campus with paint everywhere. Inside, Leonard (
Richard Erdman) attacks Jeff with
paintballs. Jeff flees and runs into Abed, who shoots Leonard. Abed takes Jeff to the base he shares with Troy (
Donald Glover). Abed and Troy explain that the prize—priority registration for classes next semester—caused the game to escalate into an all-out conflict. While they realize only one person can ultimately win, they convince Jeff to join them in order to stay in the game longer by working together. After eliminating the chess team, the three run into Pierce (
Chevy Chase) and Star-Burns (
Dino Stamatopoulos). Pierce eagerly betrays Star-Burns and joins them. Jeff, Troy, and Abed take a bathroom break but find themselves in a trap set by Britta, Shirley (
Yvette Nicole Brown), and Annie (
Alison Brie), who have joined forces. Caught in a
Mexican stand-off, Abed insists that all seven of them should work together. The group, newly unified, heads outside, where the
glee club attacks and shoots Troy, Annie, and Pierce before being shot by the other group members. The four survivors return to the cafeteria. Shirley says she would use priority registration to take morning classes and spend more time with her sons. Britta proposes that the winner should give the prize to Shirley. Jeff calls Britta phony for her proposal, but before they can keep arguing, the four are attacked by disco-themed roller skaters. The study group wins, but Shirley and Abed are eliminated, while Jeff is injured and starts bleeding. In the study room, Britta bandages Jeff's injury, and they each acknowledge each other's good sides. In the heat of the moment (and to serve the rest of the group right), they have sex there, relieving their tension. Afterwards, Britta unsuccessfully tries to betray Jeff before Señor Chang (
Ken Jeong)—employed by the Dean to take out any remaining students—barges into the room. Britta sacrifices herself to eliminate Chang, who reveals there is no priority registration and triggers several paint bombs strapped to his chest. Jeff narrowly escapes the blast and heads for the Dean's office. Outraged, he forces the Dean to give him priority registration. Later, Britta and Jeff agree to pretend they didn't hook up, which is almost foiled by Abed's insistence that something has changed. Jeff gives the priority registration form to Shirley, surprising Britta. ==Production==
