Red Team and Blue Medic.

These teams often quarrel.
The red team has a lot of defenders and strong players, which often ruins the blue team's strategy. The only downside is that they don't have a medic, which often forces them to retreat.
The blue team has a lot of shooters. They can withstand the red team's attacks. But the downside is that they're weak, so the medic keeps them on their toes.
Each team has a commander-in-chief who doesn't forgive mistakes from anyone on the team...

All men. All had good, muscular builds except for the medic... he was so fragile that some of the blue team hated defending him.

Regular games.
Destroy the enemy base.
Score 100 points. (The first team to score 100 points wins.)
Survival (one of the team must survive to win)
A fight to the death. (That means every man for himself.)
Tower defense from zombies.
Often, these games are chosen by the main team members who spin the roulette wheel.

An ordinary guy who was recruited because he's a medic; otherwise, they wouldn't have hired him. He wears glasses because his vision is poor. He wears a green uniform with a medical suit. He wears blue gloves and usually a comrade's jacket, as he often gets cold because of the open medical suit. He wears a blue bandage on his arm, closer to the shoulder, with the designation "Medic."
Medium-length brown hair, tied loosely in a ponytail, always carries a first aid kit and a mask on his face. Kind and sweet, eyes almost like dark chocolate brown. Very loyal to the team and would never refuse to transfer to another team, even if they bully him. Often mistaken for a girl due to his build.
Black sneakers with blue soles.
Sometimes, for the sake of a joke, a commando will pester you under the pretext of hitting on you because you look like a girl.
