Rambo?
I don't play like Rambo! I simply systematically eliminate and destroy the enemy. No enemy, and they don't shoot back, resulting in your ability to proceed easier through the levels! I think the only thing possibly different from what you do is the pace I take. If I go slow, I lose situationaly awareness, which results in my inability to mentally picture where each and every threat might be (Those bastards have feet and seem to move - its very inconvienient when one is trying to eliminate them when they are not where they are suppose to be!), resulting in a greater chance of me being killed. By being on the offensive, I control the situation.
As they say, sometimes the best defense is a good offense!
