ArcheAge's fourth closed beta test expanded the game significantly. Three land regions, four sea zones, siege warfare, pirates, an auction house, the Kraken, and the new Hariharan race were added for players to try out. The team also improved the look of the Ferre race and clarity during character creation. During the event, XLGAMES incorporated a Footprint system into the game that would "mark" a trespasser who attempted to steal another player's resources, such as cutting down trees.
One new feature was removed, however. The team had a combustible liquor barrel in the game but yanked it when griefers threw it into the middle of a wedding ceremony and killed everyone.
As the devs put a wrap on closed beta four, Jake Song says that they're hard at work preparing for the fifth test. Before that happens, however, the team will attempt to fix many of the bugs that popped up during the last test, improve client downloading speeds, and incorporate instant dungeons and housing improvements.
