You’ll soon be able to equip these most durable Terminators with the deadly assault cannon, iconic heavy weapon of Space Marine Terminators in the 41st Millennium. In the time of the Horus Heresy, these weapons were still new off the Forge World production lines, developed for those close quarters firefights where you absolutely have to kill every impure heretic and xenos abomination in the room.
Also on the way are new storm shields for Imperial Fists Terminators (just in case that 2+ armour save and 4+ invulnerable save wasn’t enough for you). Always masters of defence, the Imperial Fists were amongst the first Space Marines to make extensive use these personal shields, and they fit very nicely with the stoic-warrior-knight look that characterises so much of the rest of the Legion’s elite troops.
These new upgrades will be available to order soon, and will be compatible with both the resin and plastic Cataphractii kits.
