So in a nutshell, the first 45 screen boards of a possible Half-Life 3 movie or story have been drawn.  It all started with the Air-hopper craft delivering one of those resonance accelerator crystals similar to the one that triggered the Black Mesa incindent. At this point, the story board is picking up the time line where Black Mesa has not yet performed the test chamber experiment where Gordon Freeman triggered the resonance cascade, orchestrated by the infamous G-Man. Borealis and his crew have been teleported to a remote world that was almost depleted from its resources by the Combine Empire. Unknown to the Borealis crew at this point of the screen boards, and already with one first casualty, last remains of native creatures are trying to survive by making any attempt to gather their own food in whichever ways possible, more after the Combine has already exhausted the ocean waters of the planet. Borealis's crew is running out of time before the Combine and other creatures discover their location, and they are already under siege by the long-necked "giant sand worms?" (these make their appearence on the first Half-Life release)  while trying to figure out how to return to planet Earth. The Air-hopper crew is about to be also teleported, after fragments from the 'telurium' crystals left inside the transportation vault will mimic the resonance cascade already induced by Borealis. Air-Hopper's crew is beginning to notice malfunctioning of all its instruments and dials, as the teleporting moment nears.
