You embark on a journey you never asked for, facing hoards of aliens of great power, who seem to appear at will, anywhere and at any time they want. you are lead by what seems like fate, through obstacles which claimed countless lives before. you eventually cross through a portal to another world and engage in battle with a creature of immense proportions. you defeat him and just when you think it's all over, a man in a blue suit is suddenly standing infront of you, he speaks of what a fantastic "job" you've done, and how his "employers" authorized him to give you a job working in his service. He then looks to you and gives you another option, you can refuse, however he'll present you with a battle that you have no chance of winning. (for those of you who haven't noticed yet or haven't played it, this is the ending to Half Life Source)
