Startroid: Beams & Missiles

This custom-built Arm Cannon is fully modular, allowing for beam upgrades to be crafted at an anvil and inserted to power up its shot with various abilities, such as being able to phase through walls or enemies, or to even freeze enemies within place. Various combinations of beams can be toggled for complete customization.

In addition to this, it has the capability to fire missiles, if the proper module is installed. Further upgrades for missiles can be crafted from anvil and slotted into the weapon, up to a total of 4 different missile types.


The arm cannon is obtained from the Erchius Horror in the Erchius Mining Facility mission. It has a 100% chance to drop. Each beam and missile upgrade can be crafted at various tiers of the anvil, as well as with the late-game addons for the anvil (Seperator, accelerator, manipulator).


Left click shoots the normal shot, right click shoots a missile. Both can be charged, if you have the correct upgrades inserted.

Holding shift and left clicking brings up the beam customization/unlock menu, right click brings up the missile menu. Insert the beam/missile you crafted into the proper slot, and for the beams use the checkbox to toggle them on and off.


I spent a lot of time making this mod, because I wanted it to be high quality and fun to use with as little bugs as possible. I'm not going to guilt trip you into donating, no no it's fine, I'll just find some other way to make a living on my own without starving. Nah I'm joshin' ya, do what you want and as always I greatly appreciate any support I can get.

If you do want to donate, go to my patreon https://www.patreon.com/sephirothphoenix?fan_landing=true

This will help me spend more time and effort working on mods so they are released faster, and with higher quality. I do my best to work on this stuff, but y'know if someone were to *ahem* sweeten the pot (no not drugs) I would be much more motivated to work on these kinds of mods :]



Any mods that change the Erchius Horror's loot drops, such as Frackin' Universe, will prevent the Arm Cannon dropping from it. You just need to spawn it in with the id 'samusarmcannon'. Every other aspect of the mod works fine with FU though.

For crew customization+, you cannot make crew members use the arm cannon as a weapon, unfortunately.

Other than that, it should be compatible with most other mods.


I'll be working on another Startroid mod, not sure which one yet!
