So, this alternate Earth is basically the missing half nobody knew was missing. What're the joinings of the worlds like? Y'know, other than weird, wobbly space clouds and the reverse-gravity anomaly that was probably in STALKER (but I wouldn't know, because I never played the games 8D) and a few, rogue Forgotten Beasts. Are they just Stargate kind of portals, or is it as if both worlds have been stitched back together as if they're a single planet?
