[UPDATED] Though it's the same demo level, again,  this time we've made a complete list of all weapons seen in it:

This video shows the following weapons and attachments in order of appearance:

Thanks for your patience! I ended up cutting it into two parts and uploading it again to Youtube.

You noticed there where he switched you've got a different melee stance, so you had the pistol supported by your knife. That's new. We're introducing a few things like that. New melee things you might be able to do.

So it's all up to you. You can stealth your way through or you can fight your way through. I mean you noticed when you picked up the AK from the guy earlier he said: "Beware of unsuppressed weapon". And if you just go on firing unsuppressed than this whole base is going to light up bigger than coming out of the [...] woodwork after you.

Thanks Matt and xxAwpxx!

People always want more. You got the more weapons, more attachments, more locations. That's always on the top of the list, so we're doing that. Then there is, you know, they want to tweak stuff from the original one: "I love martyrdom but maybe you can change it so it's not so noobish". We're looking how we can bring that over, tweak stuff but keep the essence putting in but tweak it so it's not so frustrating.

Jessica -- So is there autosave checkpoints or can you save throughout the game at any point or you got to wait before you go through the checkpoint?
Robert -- We still use the checkpoints so you can jump out at any point, but when you come back you start back at your checkpoint.

around 02:35

There's the new AK. Any weapon that we will bring back from Modern Warfare 1 we completely redid. We have detailed textures on the weapons now and you see that Red Dot and a custom snow camoscheme. So all that we had at multiplayer, the schemes and attachments have been build into singleplayer.
