It seems that IGN has posted a brief preview of the City of Heroes Going Rogue expansion, after getting a bit of hands-on experience with it at Paragon Studios.
There is also a video with some views from the new zones in Praetoria.
Back in the old days, some of us played around a bit with creating a costume change animation using existing emotes, plus a costume change command.
Later Paragon Studios picked up on this handling and added it as a feature to the game. A few of those costume change emotes are available to everyone, but most of them are included in the super booster packs that are sold separately.
I decided to record the ones available in the game now (I have all the super booster packs), which is the video above. However, there are two emotes missing – one that is exclusive to the PeaceBringer archetype and one exclusive to the WarShade archetype. So 16 out of 18 costume emotes are shown here.
