Operation Flashpoint Cold War Crisis Demo

I guess this is off topic as it's neither new nor updated but with Operation Flashpoint 2: Dragon Rising on the horizon I thought it'd be nice to visit some of it's PC predecessors, so I tried the Operation Flashpoint: Cold War crisis demo, and it's fun, and like most things that are fun it's also hard (new forum regulations, every post MUST have a jizz, penis or old DW joke from now on .
I'd encourage everybody here to try it out as I had a great time playing the first mission, which ballsed up royally and turned into escape and evade.
The best news is, as it's so old DW's toaster can play it, one of his pretend magic computers isn't needed.
Anyways, check it out:

Some buttons you'll find useful:
V = Aim down sight
0 = Talk to command
Space = skip beginning cutscenes

Once again, remember this is a military simulator, so it's bloody hard.
