What this video covers

SKS Props walks through the full construction of Colonial Marines shin armor from the Aliens franchise using EVA foam and free downloadable PDF templates. The build covers cutting and heat-shaping foam panels, bonding and detailing, sealing with Plasti Dip, painting, weathering, and attaching a functional strap-and-buckle harness. Although the templates are designed for the USCM look, the creator notes they can be adapted for a wide range of superhero or villain costumes. The tutorial is timed to coincide with renewed interest in the franchise sparked by the Alien Romulus release.

Key takeaways

  • Free PDF shin armor templates are available on the creator's website and are adaptable beyond the Colonial Marines design
  • EVA foam is the primary material — lightweight, paint-friendly, and beginner-accessible
  • The build includes a complete strapping system using nylon webbing, buckles, and Velcro for a wearable, secure fit
  • Weathering with Dirty Down sprays and Permablood gives the armor an authentic battle-worn finish
  • The techniques shown apply broadly to foam armor cosplay, not just this specific sci-fi property
