The images seen above are from a mod called "Arctic Incident" I highly recommend trying this mod out, its about an hour play-through but it's definitely worth a play. This mod has tons of new/remixed content. Its all set in the arctic of course. The H.E.C.U and Xen aliens are present but not how you'd expect them, and there are tons of new objects to play around with. Link: moddb.com/mods/arctic-incident/d…
