Revenge of the Titans: Technology Research Guide

It is pretty difficult to tell what certain researches do or lead to within Revenge of the Titans. Certain research topics provide some useful, often vital bonuses to your turrets and mining operations so hopefully this guide will help give you some hints and tips with your research needs.

Also feel free to check out my Revenge of the Titans review.

Retribution: Collector's Edition Owners Bonus Coming...

Relic make an announcement over  the Collector's Edition and the Wargear DLC's which were available over Steam for a limited time.

"Firstly, thank you to each and every one of you for your support of Warhammer 40,000 Dawn of War II: Retribution and for making the launch a success.  

Unfortunately we did see a lot of feedback from some disgruntled customers who had bought the Collector’s Edition under the assumption that the race packs were exclusive to that particular version of the game.  While we had communicated that the race packs were not exclusive to the collector’s edition and would be available for a nominal fee to any Dawn of War fan at launch, it was never our intention to upset people who only bought the collector’s edition for the digital unlocks. 

Because we appreciate the feedback you give us as part of our community and because we value your support, we are going to be giving all those customers who ordered the Collector’s Edition a special bonus within the next few weeks.  Keep your eyes peeled for further information and in the mean time enjoy the game."
