Qb Drone


A sample, fully functional drone added to Risk of Rain 2.

The drone is powered by the API of Chen's Gradius Mod.

What is this?

A very mysterious drone of unknown origins. It is literally a cube that floats.

There is a model name and number on an edge that says...

Qb.729.216.8 - "Cute Cube".

That is all we know about it.


Lob Grenades - It seems to form grenades from one of its central nodes and lobs them. The grenades are armed, so stay clear out of it.

Close-Proximity Bomb Thing - It seems to shoot fireballs that explode on contact. It only does so to nearby hostiles with uncanny accuracy.

Mayhem Salvo - It has a weird behavior of generating rockets, missiles and mines combined at such a fast rate, all coming out from all of its nodes. This lasts for quite some time. The immense firepower is impressive.


Use r2modman mod manager to install this mod.

If one does not want to use a mod manager, then get the DLL from Thunderstore.



- Fix the hard crash caused by a Null Reference Exception.

- Update the mod so that it works with anniversary update.

- Implement Option integration for all actions of Qb.

- Initial release.

Available versions
