Warlord Games have on their website detailed the changes for Bolt Action Ver 2 over the old 1st edition.
Taken from the warlord website and can be found here
The 2nd edition offers the same fantastic World War II gameplay with its exciting order dice system and mixed armies of infantry, tanks and artillery.
Key New Features
Officers activate other units! Used cleverly, this creates a huge tactical shift as you can order multiple units to fire or advance in concert.
Big Explosions! HE fire now uses templates to determine damage – your opponent had better spread out his troops to avoid carnage!
Armed Transports! Once your squad has piled out of its halftrack, the driver can speed around and unleash a hail of lead at the enemy!
Player Feedback! We’ve listened carefully to the community and taken advantage of the thousands of battles you’ve played to improve the game in dozens of other ways.
New Army List
The main rulebook now includes a fifth army list – adding Imperial Japan to Germany, Great Britain, USA and the Soviet Union – giving you even more choice for your army.
So it looks like one of the biggest changes will be with regards to the officers and how they will command other units. From the above statement, it looks like it wont just be unit leaders activating their own units, CO’s will have a greater effect on the game. Does this mean they will become more of a target? It will be interesting to see how this will play out on the table top as this will be one of the biggest changes. Does it mean things are coming more in line with the other black books games like Hail Ceaser, in the way that orders are issued?
Another thing that caught the eye is that transports will now stay on the table and become a firebase. Poor Bloody Infantry is all I can say, they had to put up with the last tank on the table doing the same now all transports will be after them as well. I reckon they will allow each unit to take an anti-tank weapon to counter this, but I guess we will have to wait and see.
Bolt Action 2 is on pre-order for mid Sept and can be done so here.
