Having a closer look at the new Tactical Marines box, there's a new surprise for us. It features a new customizable Combi-Weapon. There's half a bolter, along with each piece to make it into any Combi-Weapon. With some clever use of magnets, you could have any gun you'd like right at hand. A pretty nifty bonus, but if you're after them in spades, look to the Sternguard Veteran box. Check them all out on the Space Marine Pre-orders page.
