Typos? Contradicting rules. Missing rules. Incorrect rules. Scenarios with bad conditions. Hidden changes. Badly written rules. The list is long dude! This is not a series of "working" releases.
Check out topics like "Blaze", "Toxin", "Charge", "Blast", "Promotions", "Advancements" and so much more.
I remember playing Half Life 2 Episode 1 and Half Life 2 Episode 2. It was nothing like this train-wreck!
I don't know how stuff "works" over at GW, but at launch 1 year ago, I honestly expected a "full game" with future expansions. It would be ok to have the gangs released later as they did, or more contents likes scenarios, a few gang-unique weapons, brutes, pets etc. This is far from what they did however. And when they originally released Necromunda in the 90s, that's what you got: a full game. I simply assumed we would get the same thing here.
