In one of the Initiation volumes, we get to see how UNSC get to pick Spartans and the process they go through to become one. The writers show us how Sarah Palmer becomes a Spartan and the enhancements made to her body.
There is also a story about Ilsa Zane, a rogue UNSC Spartan who hijacks Infinity. Spartan Zane is unique in the sense that she fights without armour and her strength equals a modern Spartan wearing a full armour. Needless to say, the hijack attempt is foiled and we are given a little insight into what is wrong the Ilsa Zane project and how she went rogue. Another volume showcases the peace meeting between the brutes and the Arbiter (remember him?) and how that descends into chaos because a Spartan informant named Vladimir Scruggs betrays the location.
The art is consistent throughout. Sometimes it feels as if they drew them all the same day. It was professional. There is nothing unique about the art to make it standout, but it is not bad by any means. They are all of good quality.
Halo: The Escalation Library Edition has loads of action scenes, background stories and almost everything diehard fans of the franchise will love. I know it's a cliche, but I highly recommend it.
