tower defense game mode with AMD

A tower defense game mode would be an awesome addition to SM2.

Inspired by the collaboration of Intel and Total War Warhammer 3 for the Mirror of Madness, you could create something epic with your recent AMD collaboration! As you mentioned your engine already has that capability, so why not use that part to its fullest with AMD support optimization for crazy custom battle scenes that the player controls.

You would have your minis factions (space marines, tyranids and chaos marines) and you would place them on a map (as they wouldnt be moving outside a small defense line it doesnt need to be big just feel big). Then create spawn points and have enemies pouring in. But also have a constant supply of allied 'creeps' (astra militarum etc)

Talents: pretty much copy and paste the already existing talents, and depending on the minis class have the talent perk work. So 1st shot outside of camouflage does extra dmg, all the minis with camouflage get it, or universal dmg buff to sniper minis.

Upgrades: extra hp for fortifications ( like the train hp pool, generators hp pool etc), extra grenades, med pads so the minis stay alive longer before being revived ( like a tower getting destroy and coming back up after x amount of time). Ability to upgrade your minis to artificer, relic, secondus etc ( statline buffs and maybe something good at the last upgrade) nerfed class abilities or make them more of a visual flare.

Pick your chapter that will load to the game from the already available ones, or! use your custom made chapters! 

In the future you could also give the people the ability to create their own settings for that gamemode! Import  maps(limited max size of course) , objects (crates, tanks that just look pretty, etc), different enemy textures, the ability to load custom stuff!

This would be the best thing for the warhammer community, you would be able to have a sandbox where you can experience the joy of tabletop warhammer but through a simulated sandbox!
