Immediately it was apparent that Six Days is not aiming for a very realistic take on modern warfare. I never did imagine that Atomic would create a plodding, Operation Flashpoint-esque shooter in the sacrifice of action-packed combat. But considering the extensive marketing on the point of realism, I certainly didn't expect to see soldiers running out into the middle of the street during a firefight, taking a half-dozen bullets in the chest, and then regenerating their health safely behind cover. Not in a planned demonstration for press, at least.
In fact, from what Konami showed us, Six Days is far closer to Gears of War than America's Army. It has the same Gears D-pad weapon selection, the same style of cover system, and the same action-oriented gameplay.
In another clip, the player broke off from his squad, crouched up behind two insurgents who were firing on US soldiers, and took them out from a few feet away like some kind of renegade commando. I may be ignorant of this particular battle, but I've certainly never heard of any Army ninjas breaking off from their squads and capping insurgents solo. Maybe something like that has happened once or twice; either way, the videogamey nature of the moment seemed entirely out of place.
Later on, a soldier fired a rifle-mounted M203 grenade launcher into a building--then fired it again, and again, in a rapid-fire Rambo tactic that you'd only ever see with a controller in your hand.
We didn't see any of the moral choices or "survival horror"-esque situations that the developers have mentioned. All I saw were scenes straight out of a Battlefield game. And unfortunately, the liberties taken in this early demo immediately called into question the rest of the game's merit, and turn the whole project into the sort of controversial mess that nobody enjoys.
