I would recoil in shock, baffled at what has become of this unholy object thrust upon me against my will. I would clutch it with the most furious anger, and ascend Mt. Olympus to curse the Gods and Zeus himself for afflicting me with this atrocity, so violently forcing this game upon me that I did not ever request.
I would heave the cursed object into the scorching magma of Olympus itself, and myself along with it to assure it's destruction.
If I survived this adventurous onslaught of terror, I would then come back home, get a Snapple from my fridge and pound my melted fingers against the keys to demand the Halo: Reach threads to cease, once and for all. Lest I be imbued with the power of the Gods from my feats of sacrifice and bravery, to smite you all mercilessly, and without end.
