Over in the Dawn of War 2 community forums under each race sub-forum they each have a replay thread where you can upload game replays for others to watch for tips, seek advice, or just post cool games. I figured we might as well start one here as well.
 
To upload a replay all you need to do is A) Save a replay.(Once the game is over, in the post-game lobby click the "Save Replay" option) B) Head over to http://www.gamereplays.org/dawnofwar2/ and create an account. C) At the GameReplays site click on the "Upload" option under replays. D) Find the file in your Dawn of War 2 folder for the attachment, fill in the blanks and upload the video.
 
As for replays that I've uploaded the most recent one that I had put up was a really close 2v2 game between Myself(Tyranid) and my friend(Chaos) against two enemy Chaos players.

I'll add more if I can find any more close calls or anything entertaining, feel free to add your own too.

Huh, idk not the best game i've seen. Both sides took wayy too many losses for not a whole lot of gain. Also no chaos used worship that well, while your friend did in the beginning it wasn't that great. Also idk why he waited for Great Unclean one, not that great. I'm not sure why you went tyrant guard, the genestealers are great, and do massive damage. I would use hive tyrand to get close and disrupt them then bring in the stealers with some support with strangler warriors. Also you both floated alot of req, and when you did build power you did it wayy to close to the base and gave them 3 gens, build it closer next time. Nice job dealing with the turrets though.
