I never got into Zone back when it was a PC Server.
I was attracted to it initially because Blookat and Dell were there, but I was quickly put off by the 8-direction firing, scripted(faster) projectiles, and Graal Kingdoms-style bodies. This was like 2005 or 2006.
It was great concept though. I really liked the fact that one world was like a repetitive event where two teams compete to take bases. The scooter-bikes were a nice, aswell as the different classes.
But no, Zone has nothing to do with Era.
