An fps that has an actual scene where you and the enemies are setup on both sides of a field. The scene goes as you rush over the side of cover and make towards the enemies, while the enemies do the same thing. As you are doing this, people are shooting guns, artillery shells are exploding all around in realtime, none of the predetermined **** craters are made in real time, and there's gunsmoke almost entirely obscuring everything.

I don't care what the setup is, hell, it could be that the dog monster king was angry over the Sewer munshkins dumping all their left over hair into buckets and throwing them into his doggy palace so he sends an army of heavily armed rambo clones after them as the sewer munshkins send an army of robotic gun walkers where they eventually meet up on a field, I don't care, I just want to have a scene like this.
