Isaac Clark vs. Marcus Fenix

Isaac Clark has level 3 armor, a flamethrower, plasma cutter, and a pulse rifle.

Marcus Fenix has a lancer rifle, shotgun, and pistol.

Fight is onboard the Ishimura and to make the fight interesting, a few Necromorphs will attack the two after every 20 minutes.

Who wins?

So am I gonna guess that nobody likes or knows any of these characters?
