Optimus

Optimus was perceived to be a second Bot Nuke originally planned for release in March, but was delayed until May 3, 2012, when Jagex implemented it.

It will now be implemented on July the 14th.

Game Engine & CM Q&A
Mod Philip confirmed in the Game Engine & CM Q&A of 13 April 2012 that they are working on Optimus and that they also have other things planned to stop the bots.

In that same Q&A Mod Chris E said that Optimus is close to release and that it's related to the FPS fix as Mod Mark said earlier.

3 May 2012 update
The anticipation of Optimus being another Bot Nuke in May had led to large fluctuations of prices of various items in the Runescape economy. Due to the increase in value of resources commonly gathered by bots, many "merchers" had sold their traditionally-held discontinued items, in hopes of gaining a profit with the uprise of resources, thereby causing a dip in the price of discontinued items.

There has been much speculation on the target of Optimus—although widely believed to be aimed at only bots, Optimus was, in fact, an update to the game engine that allowed it to be easier for Jagex to implement systematic changes easier.

The update on 3 May 2012 included the Optimus platform.

Optimus Part 2
A second bot nuke is planned to be released on July 14th 2012

There has been a debate about whether the next bot nuke is called Optimus or not. However, Mod Tom B has confirmed it to be the second part of Optimus.

The Bot Nuke will target the more popular injection and reflection bots, and removing colour bots will be a side-project - as shown in the quote by Mark Gerhard above.

It has been percieveed to be a good investment opportunity for merchants.
