when playing a game of cities of Apocastrike death (yes it is a combination of all three and rocks!) i came up with an idea (actually 2 but my awesome idea for a rhino carrier isnt as fun) When looking at a forgeworld reaver titan i thought - wow thats awesome i love that powerfist - what if it had 2? - and so the idea was born...
The corsair class titan is a design thought to have first been used in the middle of the horus heresy - to directly combat a khornate titan - however its speciality widenened during the horus heresy so that as well as combating titans and large vehicles it could also combat individual enemy infantry targets (primarchs spring to mind) this was achieved by the weight saved on ammunition from the carapace mounted weapon - as well as this the reactor in the Corsair is used to power additional void shields - due to the energy saved from getting rid of high energy weapons and their targetting systems and all this weight loss improves the manouverability of the corsair further so that it can almost match the speed of its eldar counterparts even with the weight additional armour adds.
so thas my idea im currently working on some rules for it but all feedback would be appreciated..
