We've all got those gimmick ideas for Space Marine Chapters that we think of but never post because they're too... Memetic. Let's toss all those ideas into one thread and see what sticks.
>Blood Hounds: Marines with a Gene-Seed Mutation that gives them the ability to smell Warp and Warp-taint. Recruits directly from the Inquisition.
>Trench Marines. Guardsmen that never stopped being Guardsmen even after they became marines. Really supports the 8th edition standard of Marines+Cover.
>Druid Marines: AdMech Marines with a focus on Bio-engineering and Terraforming. Basically in charge of repairing the planetary environment after an Ork infestation or Exterminatus.
>OP marines: bunch of faggots that always try and force their topic in conversation.
>Sub Marines: Slaaneshi Marines obsessed with finding the PERFECT Sandwich... or crafting the Perfect Sandwich from certain... found ingredients.
