This game was actually not available to buy legally anywhere, but it's finally on GOG.

Give it a whirl if you never have before! Arguably one of the best FPS' on the PC where you control your own SWAT squad to respond to various missions. Less-than-lethal, tactical approaches are welcomed, methodical approaches and pre-planning depending on scenario is necassary to succeed.

Also recommending the somewhat fresh Elite Force mod that rebalances the game and re-adds cut content.

Hey there. Thanks to the people who found this group themselves, it's been made recently and has pretty much no promotion.
I've been asked by Tim to start this group up myself after I asked him about a steam group via email. Invite all of your GHG friends.

I'll try and generally keep this group alive, as I am a great fan of GHG content. Tim also has officer related powers and governs the group pretty much on the same level as I do.

I hope this group gains a little momentum, most content and updates are posted on the Twitter by Tim, so check that out too, but I hope this gains enough members to be a viable gathering for the Greenham followers.

Thanks!
