Lost Eden adds a whole new element to the way
Anarchy Online is played. Players now have the option to distribute the experience points they earn into a new "research pool," which allows them even more character customization than before. On top of that, they can choose to help out their side (Omni-Tek, rebel clans, or the neutrals) by researching weapon upgrades, specifically for the new mechs.
When the first expansion, Notum Wars, was released, it added the area of mass PVP, while players from opposing sides would try to fight for control of tower spots, which added bonus to the players who owned them. With Lost Eden, the new mechs and space-stations added a different aspect to the battles: tactics. No longer can players win by sheer numbers alone; they must now coordinate and plan ahead as to how many mechs to bring along and whether or not to use the space cannon (as it costs Victory Points to use).
Now, with the new mechs, players whose characters weren't specifically designed for PVP can now help out, as mechs are now a vital part of PVP. But players should still be weary of other players wielding rocket-launchers specifically designed for taking down the massive mechs. Mechs were a great way to add balance to the PVP system.
In the third expansion pack, Alien Invasion, players had the option to build cities for their own guilds, or organizations, as they're called in this game. But, with the new cities came a new threat: aliens. It's still unclear where these aliens originated from, but it's obvious that their technology is far superior to those on Rubi-Ka. Originally, the players could only be attacked by the aliens. Now with Lost Eden, players have the option of taking the fight to the aliens. This was one of the biggest selling points to the player base, as many of them didn't want to have to join an organization to enjoy the alien content. Now players can pick up a team, and not miss out on the alien content.
