3 Commando Brigade

There is a God (Swat 4 is now on GOG)

As the title said, Swat 4 is now on GOG. I've already played it and it is fully funtional (even the coop works, yay)
If you are not familiar with Swat 4 it is a fps in wich you have you plan your movement very carefully. I think there is no better cqc simulator than swat (you dont fall through walls, doors, floors and every corner could be your last, if you dont pay attention).
Swat 4 has a campaign, that can be played in singleplayer and 4-player-coop and i think, that is realy what lets this game stand out. The Missions range from a restaurant raids to barricaded hostage situations with heavy armored fanatics.
The Arsenal ranges from Pepper-Ball filled Paintballmarkers to a M4. Dont expect a graphical masterpeace because the game is from 2005 but the gameplay is on point.

I've uploaded a mission from the addon (wich is included btw.). I played it singleplayer, but you can play the mission 1-1 in coop.

This looks rad man, I'll have to get it and we can play some time!

Spent a lot of time on it back in the day. Who hasn't tried, definitely must try it out.

I had SWAT 3 (which was great and very hard, if a little buggy) but missed out on SWAT 4 during its heyday.

By the time I got around to it it was obsolete and nobody was playing it. 

this is game is so awesome,
let me know if you want to do some coop

Thanks for posting this! SWAT 4 is one of the very few physical game media I keep around, but last time I tried the game (a few years back, on Win8, iirc) it wasn't working too well. 
I played a lot of SWAT3 and SWAT4 but I never got the AddOn for SWAT4... Really looking forward to playing this game again!
