The alpha version of Planetary Annihilation is set to perform an orbital drop to the Earth's surface sometime this month, but in the meantime developers Uber Entertainment have done a big old livestream showing how combat is shaping up in the RTS with the ridiculous sense of scale. Spoiler: it's looking rather exciting, with clear iconography giving way to more traditional detail when you zoom right into the planet's surface. Also: terrain deformation/scorch marks, which always makes me do a happy dance for some reason. While it looks the part, however, there's still a ton of inconsequential, two-minute-job stuff like AI to program, which will hopefully be in there when the alpha annihilates our PCs this May.
You'll need to scooch along to the 7 and 1/2 minute mark to reach the gameplay footage, but it's worth wrestling with YouTube's maddening timeline controls. As RPS note - thanks RPS! - Uber also did a live Q&A on the same day. You can find it not-live below.
