<whoop! whoop! whoop!>
Finishing out the week with a Giant Robot Alert. And considering that this is a 40k titan, it's one of the giantest giant robot alerts. Forge World is taking orders for the new Macro Gatling Blaster for your Titans, as well as a Titan bundle where you can get the whole thing in one swoop.
From the website:
The macro gatling blaster is a monstrously destructive weapon, capable of firing thousands of explosive shells in moments, deluging foes with armour-piercing rounds that will leave them pinned and ready to be assaulted – if they're lucky enough to survive the volley.
In your games of The Horus Heresy, the macro gatling blaster can be fitted to the arm of Warlord Battle Titan, providing you with enough firepower to destroy the most heavily armoured vehicles or utterly annihilate unfortunate squads of infantry.
This multipart resin kit includes 15 components to construct one macro gatling blaster which can be mounted to either the Warlord Titan's left or right arms. Build your complete Titan with the Warlord Titan Builder.
The rules for using the Warlord Battle Titan and the macro gatling blaster can be found in The Horus Heresy Book Five – Tempest and the Horus Heresy: Mechanicum – Taghmata Army List.
