Grimlock ♥ Ultra Magnus

Infestation had problems, mostly that it was part of a larger thing and I feel like you don't get the whole picture when the two Transformers tie-ins - and they were all tie-ins to media like G.I. Joe and Star Trek - when just the Transformers issues are included here. 

And Britt was just ridiculous. 

Seeing Transformers vs zombies was kinda fun, though. 

Volume 2: 

Two got more interesting, as it involved details of how the world in general reacted to Autobots given the events in All Hail Megatron.  There's also collusion between Spike Witwicky - who was changed to Sam in the movies - and the Autobots.   

There's also the Spike and Scrapper issue, which will come back to haunt him later on.   

It's also not as nuanced, or balanced, or just plain good as phase 2, and this remains that way until the end.  If I remember correctly, phase 1 gets worse and then we get phase 2...

Volume 3:

Probably one of the more interesting volumes: Megatron gets a new body and turns his old one into guns.   That he gives to humans.   It's all about getting back at Optimus Prime and the Autobots by getting the humans to turn on them.   Some already have, some need a little push, but the thing is that Prime and the Autobots still insist on protecting the humans.   This is to prove how foolish they are for caring.  

And this also sets up a lot with Jazz, who kills a police officer - on live TV - to protect Bumblebee.   One of the problems?   Bee was already talking him down.   

I think this may be my favorite of the volumes in this series.   But still not nearly as good as phase 2.   Still, volumes two and three will come back into play pretty heavily for phase 2.  

Ironhide: 

Man, I kinda like that he came back, but... I don't buy a lot of this volume.   Like that Alpha Trion could bring him back, like trusting what he did to Sunstreaker, like if this is possibly why doesn't Alpha Trion bring back a bunch of people?    Isn't it worth the time and effort?

Anyway, yeah, Ironhide on a mostly dead Cybertron fighting Insecticons. That's pretty awesome.    Also, you get some insights into Ironhide and how he joined up the Autobots and why, and that's nice, too.
