That House

You find yourself barricaded in a house, facing a crowd of armed enemies, who are coming for you. You have only one objective: Survive! Forget the complexities of military operations - in this mission you can just go trigger-happy.

The idea:
1) Watch the intro
2) Enter the house
3) Arm yourself to the teeth
4) Fight for dear life!
5) Run as fast as you can.
