Well I just picked up my June WD today and of course flipped directly to the Spearhead section (well, first section, some genius decided to spread the Spearhead stuff throughout instead of in one section). I wasn't sure what to expect in the way of length and depth as it has been some time since WD actually published rules supplements, but I sure was mighty excited. Anyway, here's a quick overview:
-the actual Spearhead rules themselves take up about 8 pages, including the new Force Org chart and the new "Spearhead formations" along with it.
-a "Spearhead Formation" is taken separate and outside your normal force organization. You may take up to one Spearhead of each 'type' (12 types in total, found on GW website)
-not going to get into details but just for anyone wondering, yes you can use all the other troop types (infantry etc) in your Spearhead games. Obviously with altered Force Org though.
Example: Tank Hunters Spearhead - 60 pts + models (up to 3 tanks/walkers), gains Tank Hunters rule
-the last half of the article consists mainly of missions, deployments, and the like
Personally, this looks like a pretty top-notch supplement for being essentially free. Brings a unique and interesting new style of gameplay that is entirely optional for players. So people who love tanks can have the battle they dreamed of (outside Apoc) and everyone else can go on as they were.
So what does everyone think of this expansion?
Also included in the issue:
-a Spearhead-related "Liber Apocalyptica" article: Spearhead in Apoc. games and a bunch of new formations (mostly Eldar if I remember correctly, maybe all)
-rules for the Eldar Night Spinner (with a NS formation in Apoc section)
-article on choosing a BA army list
Overall for me this is the best WD in recent memory, I highly suggest you pick up a copy!
