Survival of arcade-esque shooter battle
This is a question for anyone who has gotten past this level: When the character Warren is finally met, there is an arcade style shooter battle in which the Special Forces of the Company are swarming in the room. The weapons I have available are the hammer, pistol, shotgun, assault rifle, flamethrower, and three grenades. The SpecOps troops with assault rifles enter in through the main door adjacent to the windows and some flamethrower troops enter through a door on the wall adjacent to the wall with the windows. So far I've tried grenades to blast away the first three waves of assault rifle troops and then finish off the flamethrower dudes with the assault rifle, and then I tried to just incinerate everyone, but some are too far away and they ebb away my health points from a distance so that I basically have lost this level twice. What would I need to do to beat this level?
