Raid Bosses

Hi
first of all i have to say the map is awesome so far. Just discovered it 2 Days ago with some friends and we already kill all avaible Bosses on Normal Hard and Extreme. Now I have 2 Questions. We all did beat all Bosses avaible so far and still the Raid Bosses are locked. Are they implemented already or not? And if they are implemented already how to acess them? And my second Question is after a look on the Achivment Page i found achievments for 2 Bosses i didnt find are those kind of hidden or just in pogress of implementing and you simply did the achievments first? Thanks for the Answer in advantage

The raid bosses are not in game at the moment. I'm nearly done with the colosseum which will be the place of raids and other events. This is a huge arena in a terran city. The 2 achievements will be added into the game when the final tier 3 boss gets added. Hopefully within a week. Thanks for your concern.

I believe a good raid boss could be the terratron. it is allready a boss in the arcade game, why not here?
