The jungle territory of Hossin won't arrive in Planetside 2 until May but the Amerish region is changing right now. A major revamp was implemented just before the weekend, adding nine new outposts and redesigning those that were already in place. Most significantly, perhaps, the Lattice System is now in play on Amerish, meaning that conquest of outposts must be conducted along supply routes, as on Indar and Esamir. A more strategic first-person space-biff awaits. There are other tweaks as well, including an increase in resource rewards and improved roads. The appearance of the continent has changed as well. Judging by the before and after shots in the video below, the forests and mountains no longer look like they've been plucked from Earth. It's all a bit more sci-fi.
Hmm. I actually prefer some of the 'early' shots, although that's because they respect scale and distance rather than showing close-ups of leaves and purple crystals. There's nowt more alien than a glowing purple crystal though.
All the info is here and the update is live at this very moment.
