The art has been pretty... not good. I've found that a lot of the Halo comics don't look as good as they should, but this series in particular is just bad. I don't know if it's just the tight deadlines or what, because Omar Francia isn't a bad artist, his work on the Mass Effect comics is pretty great. However, in Escalation there's only two kinds of faces- which look nothing like the characters in the games. Also, the designs of the things not seen in the games stand out as generic- like the Covenant laser beam station or the civilian clothes. Vata 'Gajat looks interesting, but that's because his armor is based on Halo 4 concept art.

I want to like Escalation, but with comics being so dependent on visuals to tell a story, it hurts the narrative sometimes.
