Entering the facility you could choose many different approaches starting with your weapon loadout. Melee weapons, small arms, and non-lethal weapons are all available, the Eidos-Montreal rep chose to take a stealthy route and went with a tranquilizer gun. Moving through the building we could immediately see that there were a few options. You could try and tranquilizer all the guards and head in the front (risky) or search for an alternate entrance. Exploration and a quick use of the sight augmentation (which has a very cool X-ray vision mode) showed us there is a maintenance tunnel we could use.
Entering the building proper they took cover behind walls and snuck up on guards, they chose to do silent non-lethal takedowns which were very cool indeed. Every area seemed to have multiple paths whether you could go the direct route headlong into the enemy or small entrances through vents or via rooftop access. This gives a great deal of control to the player as any challenge can be approached from many different angles.
The presenters also showed us how you can change your augmentations to tailor yourself to the mission and how you want to tackle it. Because they wished to take a silent approach they amped up the vision mods and battery power so they could plan their infiltration better. The demo also gave a us a great look at the vision modes, inventory, weapon and augmentations, all of which look very cool.
To change the pace of the demo they loaded a save file that had Jensen setup as a guns blazing war machine to show off the combat. The engine is very capable as both a stealth game and a shooter. Every time you get to cover it switches to a third person view seamlessly and really lets you take stock of the situation. Armed with multiple weapons and retractable blades they proceeded to wreck havoc on the enemies and the environment. A great deal of the objects could be shattered and torn up and the weapons seemed to have a really visceral feel to them.
