The combat looks simple and sharp - less intense than Killzone 2, less muscular than Gears of War, but a bit more clear-headed and tactical, with contextual team orders available to make the most of the other Delta operators.
Walker leans out or blindfires from behind abandoned Bentleys and sports cars, and enemies crumple as they take the hits. One man receives a shot somewhere near his jaw and clutches his face as he falls.
The skirmish is soon over but there's a larger one waiting ahead. The team becomes locked in combat with a larger force and Walker busts out some moves - kicking a guy in the face pretty slickly as he vaults over a low barrier.
The bad guys ahead are standing close to a series of huge concrete plates against which a huge tide of sand is leaning. They're also perilously close, it turns out and when Walker throws a sticky bomb at a nearby soldier he flees in their direction, explodes and brings the wave of sand washing down over them. By the time it settles the music has stopped too. Silence.
Enemies will be able to pull sand tricks on you too, the developers warn. With much of Dubai submerged beneath the stuff, you're often walking on glass or something breakable, so undermining's a potential hazard as well.
Spec Ops isn't finished setting the scene though. As Walker proceeds down a gully formed out of some of those precarious concrete slabs from earlier, the guys end up ankle deep in dead bodies. They emerge onto marble floors beneath huge vaulted ceilings, but also into a scene of horrible destruction as white phosphorus rains down on refugees fleeing Konrad's soldiers.

An outpost of progress.
Spec Ops: The Line is free with any purchase.
As the former citizens of Dubai writhe and burn, Walker and company advance and sneakily manoeuvre behind a trio of slow-moving enemies who are checking for survivors. They don't last long, and then it's up a recently formed hill of sand to a window overlooking a square.
Down below Gould has been captured and is being interrogated. He won't give up the information his captors want, so they bring forward a young woman and throw her to the ground. One soldier then holds her down while another fires his assault rifle into the ground right next to her face until she suffocates.
It's not clear if Spec Ops is gunning for BioShock levels of choice and consequence, but the developers claim there are key decisions to make that have repercussions later on, and in this case you can choose to headshot the man leading the interrogation. You can probably also save Gould.
For now though we're at the end of the demo, and Konrad's voice booms over the fade, taunting Captain Walker. The developer's voice then booms over Konrad's, informing us that the game will also include competitive and co-operative multiplayer (there's an ongoing beta on Xbox Live at the moment, in fact).
Spec Ops is still early in development, apparently, despite having been announced last year, but the signs are promising. It may face a lot of competition in the shooter genre (BioShock Infinite's looking quite good, don't you know) but the combat looks interesting, the story partly based on Heart of Darkness, and it's nothing if not provocative.
Spec Ops: The Line is due out for PC and Xbox 360 next year.
