Black Legion: Chaos Space Marine Codex Supplement... $39.99 off of iBooks.
1 - 5 Ranking (1 = Low, 5 = High): 3... Or so...
Overall, the iBook supplement has a lot of great fluff and story content that follows Abaddon's rise into the Warmaster of Chaos and his transformation from Ezekyle Abaddon to Abaddon the Despoiler. It details, in chronological order, all of the 13 Black Crusades (to include the start of the current 13th one), however, each topic is covered in just a few pages. All in all, if you've read the Wiki's and other Black Library books, etc, a lot of the information presented is somewhat familiar, but some of it is very new & interesting.
It presents some very minor artistic, drawn images of what a
CSM from each of the Black Legion's Warbands looks like: Hounds of Abaddon (Khorne), Children of Torment (Slaanesh), Sons of the Cyclops (Tzeentch), Bringers of Decay (Nurgle), The Tormented (Possessed?), and The Oath Broken (Legionnaires who failed Abaddon in battle and now have cybernetic augmentations; completely aesthetic no actual unit enhancement). None of these Warbands have any specific rules or anything more than a brief description of who they are and a picture of them in the typical Black Legion color scheme, but with a highlight of their Chaos God's typical color thrown somewhere on their armor (Red, Purple, Blue, Green-ish).
Next, the supplement has a lot of individual, interactive iBook photos of every miniature in a Black Legion color scheme. Overall, I like this due to my artsy desires and my attempts to replicate a similar looking mini.
Moving along, it adds in the additional rules. Most of these rules are not far fetched and could have been imagined in someone's House Rules. In a Black Legion Army -ALL- Chosen are Troops Choices, all units in a
BL Army that can take VotLW -MUST- take VotLW, and if you take Abaddon as your Warlord you can upgrade a single unit of Chaos Terminators to 'Bringers of Despair' for an extra +6 points per model. This upgrade simply gives the Chaos Termies +1
WS & +1
BS. We also have some new (and frightfully powerful) Chaos Artifacts: i.e. 'The Hand of Darkness', S x 2,
AP 1 with Melee, Armourbane, Fleshbane, Instant Death.
Finally, it introduces several new Cities of Death & Planet Strike strategems as well as some very interesting Altar of War mission types (3 of them). And then it closes out the book with several other missions that can be played that put the player through some of the historical moments of the
BL.
All in all, it's great for some extra fluff, however, the new rules, etc, I found were to be a bit lacking. Nonetheless, I am a fervent Black Legionnaire myself, so I can't say I hate the book; it was a bit disappointing for what I hoped, but it will not stop me from using. It's okay, but probably not worth the $39.99 I paid for it. Maybe $20...
