You play as Red or Blue.

Red and Blue were just doing their work, sleeping as always. Until Noobador barged in their room, interrupting their sleeping.

[Noobador]: c'mon, wake up. we're gonna go outside.

[Blue Noob]: You're just in time to wake us up!

[Red Noob]: 'Cause we're RED and BLUE!!!!

[Blue Noob]: And we'll crush them!
