Modern Warfare 2GAME.OVER!
After getting betrayed in Russia, switched to my troops in Afghanistan who were similarly betrayed but still alive. Raced to meet with my teammate while in the middle of a battle between the US army and the Russian Insurgents. After a difficult rush and a heart-racing drive, managed to drive onto an awaiting plane to escape.
MOved on to a secret desert base to confront our betrayer through intel from the russian insurgent we were originally fighting. Enemy of my enemy indeed... We were discovered and had to fight through some very pissed soldiers, surviving a self-destructing base. Our target kept evading us, ending in a boat-chase. After some rapids, dodging rocks, shooting down his helicopter, and going over a waterfall, we all somehow survived. My guy tried to kill him but got stabbed and could only watch as my friend continued the fight while I yanked the knife out of my gut and through it in his face.
Our friend rescued us and the game ended...
Wait, what? Over already? I'm not even talking time, I'm talking story closure. We killed the US general, got branded as wanted terrorists, and the actual terrorist is still alive? At least end the damn story instead of padding for a sequel.
