According to Rebellion Studios lead programmer Richard May, making something new feel retro is more complicated than it sounds and "recreating the glowing green lines using our modern in-house engine required some workarounds." The controls, on the other hand, were a little simpler to rebuild since the team had already built out the two-track control system of the original arcade cabinets. And one more thing that's not changing: you still can't get any closer to that danged volcano in the distance.

In addition to Classic Mode, the free Battlezone update also adds new missions, levels and a game codex. The whole thing rolls out on December 20th.
