Manehatten 2033

Rainbow opens her eyes to see Flash Sentry supposedly getting attacked by a Dark one. The background was white so she had no idea what was going on.

"Aahhhhgh" Screamed Flash Sentry.

Rainbow Dash wanted to do something. But the Dark one prevented her from moving and she saw the light.

Rainbow Dash woke up to find them  making their way through the tunnel at a decreasing rate. Rainbow Dash swore they weren't out for that short of time. Any longer and they would've stopped right in the middle of the tunnel.

"Huh?"

Rainbow heard the sound of what appears to be a nosalis.

"Wake up AppleJack!"

Rainbow Dash rapidly shook AppleJack trying to awaken her.

"Wuh what? Oh shit!" Shouted AppleJack quickly pushing the lever to speed up the cart.

Suddenly in the distance AppleJack spots a group of Nosalises catch up to them.

"Shoot them! For the love of Celestia, Shoot them!"

Rainbow Dash leveled her Bastard and proceeded to shoot the incoming Nosalises, Few of which managed to jump on the cart.

"Here take my shotgun"

AppleJack passed a Duplet double-barreled shotgun to Rainbow Dash who proceeded to continue kill off the Nosalises. Albeit more effectively.

"Damn Flim should've given me a Duplet." said Rainbow Dash.

Suddenly one Jumps onto Rainbow Dash and attempts to kill her. Press X repeatedly.

"You want to fight me?" shouted Rainbow Dash who pulled out her knife and Decapitated the Nosalis' Head.

Another Nosalis jumps onto the cart, but instead jumps onto AppleJack.

"GET IT OFF ME!!"

Rainbow Dash grabbed one of AppleJacks Grenades, lit the fuse, shoved it down the Nosalis' Mouth and kicked it away from the cart killing the Nosalis and half the Nosalis horde

Suddenly a Nosalis Jumps up and manages to bring Rainbow Dash off the cart and down to the ground. Rainbow Dash quickly hid in a nearby hole in the tunnel while the rest of the Nosalis ran past and suddenly died from gunshots.

"Wait! I'm still alive!" She shouted.

She quickly ran up to where the cart had stopped before the flamethrower was put to kill of any remaining Nosalis.
