Can someone explain Bolt Action to me? Or point me toward a good write up?
Bolt Action is somewhat similar to 5th Ed 40k, except for two big differences. The pinning mechanic and the turn system. If a unit gets hit it sufferes a pin. That pin affects their ability to do anything. The pins are minis modifiers if they try and shoot, and They must roll a morale check every turn to carry out an order, with a modifier of minus however many pins the unit has. This means that you can effectively take a unit out of the game without killing it if you get enough pins on it. It doesn't sound like much, but it has massive in game effects.
It also doesn't follow the traditional you go-I go system. Every unit has an order dice. Both players put their dice in a bag, and randomly draw one. Whichever players dice is drawn gets to activate a unit. This makes the game a lot more tactical, and a game can be won or lost on a single draw of the dice.
