The Runescape Monster Release

The RuneScape Monster Release happened on December 19th, 2007. Jagex did it to see if players or monsters were stronger.

Background
Jagex realized in order to see each side's full potential they would have to cram all players and monsters on a single world. It took 3 years, but Jagex did it. Members and non-members would be on a same world. Members would also be able to use their member equipment. On December 14th, Jagex posted on the front page of the upcoming monster release. They said all monsters would be coming from the Wilderness. They said that on the 18th there would be only one world until the event was over. Signs that the release would be coming would be like if there were no monsters in places they should be in (like no monsters in Stronghold of Security). At 12:00, December 19th, 2009, the monsters were all teleported to the Wilderness. Random NPCs would be shouting that the monsters are coming.

Resitance
Swarms of monsters came crashing down. Varrock was hit hardly. The monsters used teleblock on Varrock. They also laid siege to it. Anyone in Varrock was stuck. In Falador, Elvarg came. Witness say Falador was literally on fire. The monsters could also run faster than players. They came all the way to Lumbridge. The noob army was slaughtered. People were killed, and they ended up in Lumbridge. In the first few minutes there were at least thousands of people ending up in Lumbridge, Falador, and Camelot each second.

The end
After two days, Jagex stopped the monster release. Monsters were too powerful, so that's why there is a lot of good stuff in Runescape now.
