XCOM: Enemy Unknown's original pitch video revealed

XCOM: Enemy Unknown's release next week marks the return of a franchise in hiding for over a decade. But, how has it changed since its inception? Developer Firaxis Games has released Enemy Unknown's original pitch video--the same video used to get publisher 2K Games on board the series revamp.

Many similarities to the final product can be seen, but there are a few differences. For one, the camera is much closer to the characters, and movement is severely restricted. Additionally, there's a time gauge that lead designer Jake Solomon says ended up making the game "too slow."

While there are subtle changes, it is impressive to see how much the game has retained over the years. The full video can be seen on IGN.
