I'm toying with making a US Colonial Marines themed Guard force based on the Aliens, Prometheus and Predator films.
I've just bought a crate of disgustingly sexy Elysian Drop Troops from
FW and will be using them to convert the marines. The
FOC will run as a clean mech-vets list with Ordo Xenos / Tempestus allies. This is mainly going to be a chance for me to get my painting up to scratch and bash out a couple conversions. I've also ordered the US Colonial Marines Tech Manual which is the holy grail of inspiration

and have got my hands on some juicy 28mm M41a Pulse Rifles courtesy of Hasslefree Miniatures
The colour scheme will be the standard olive & drab (Cadian 8th for you old timers)
Here are some ideas so far:
- Navy themed
CCS &
MoO
- Engineer themed Inqusitor Lord
- Elysian with various Catachan head swaps, bare arms, bandanas, SMGs and M41 rifles
- 28mm Smartgunner (Sgt. Harker proxy)
- Weyland Yutani Commandos (Tempestus Scions)
- Synthetics
- Predator Eversor Assassin
- Xenomorph Arco-Flagellents
- Exo-combat suits and "Power Loaders" (Ogryns or Sentinels?)
- Alien eggs as Objective Markers
- Facehugger Servo-Skulls
- Penal Legionnaires (Aliens 3) & Weyland-Yutani Mercs
- Various tanks, Valkyrie gunships, APCs and Mechas
- LOTS of Sentry Turrets
I saw a few similar threads from a couple years back but it would be great to hear your suggestions too.
Ooh rah!
