A MLP/TF2 Crossover.

Rainbow Dash has been busy lately. Every waking moment not spent helping creating the weather or helping save Equestria is spent in her house, her bedroom, playing a video game.

That game is Team Fortress 2, a game of battle, skill, and weaponry, and Rainbow can't get enough, she is addicted. But there is a small problem: spending so many hours in front of a computer screen isn't helping her image of uber-athleticism. And there's no way she would tell her friends about this magnificent piece of gaming.

Unfortunately, she no longer has a choice in the matter, when Discord decides to give Dash a taste of her own pranking medicine. However, this doesn't go down as Discord planned, as now he, the Six, Spike, and Big Mac are trapped inside the game itself.

Now they have no choice but to join the Soldier, the Heavy, the Medic, the Sniper, the Engineer, the Scout, the Pyro, the Spy, and the Demoman of the Blue Team in their never-ceasing warfare with the Red Team. How exactly are the Equestrians going to get back home, and what will they learn from their experiences, if the experiences don't tear them apart first.
