"See, if you were smart you'd understand how to do that part" - James
Battleblock Theater is a series where James and Aleks bring back and play the classic and beloved game, Battleblock Theater, a game that depends on teamwork and cooperation in order to complete the puzzling levels.
"And now I pulled it out. Look at that." (James) "Wow you pulled it out...it's so huge" - Aleks
"I'll go up and down on you" - Aleks, to James
"See, if you were smart you'd understand how to do that part" - James, to Aleks
"I feel like a rat in maze dude and I'm talking to another rat like "Yo what do you think of this?""- Aleks, to James
"I can't get on the black one!" - James
"My ass got burnt! I was on the ladder and I was like "I'm safe here" and my ass got fried!" - Aleks
This game was also the predominate game series that made the duo of Aleks and James popular (Mainly since James originally played/collaborated with multiple other YouTubers before he and Aleks were regarded as Co-op Partners).
