The level EA's currently unveiling is a night assault on an enemy-held mountain. The landscape is strewn with broken rocks and scrubby little patches of grass, the only light comes from distant campfires marking out enemy positions, and, playing as part of a squad, you're a Tier One advancing slowly into dangerous territory, with only the dark shapes of your nearby allies - and their precise, whispered commands in your earpiece - to keep you company.
The first encounter with the enemy is emblematic of the way you'll approach situations as an elite soldier. A gaggle of distant forms are gathered around a flickering campfire. Rather than wading straight in, your squad fans out around the edges of the area, each taking a target. It's a process that takes a surprisingly long time, given the zany pace of most action games, but it's all the more tense for it. Then, with just a few shots - resoundingly loud on the echoey hillside - everyone sat at the campsite is dead, and you're off again, moving further up the mountain.
