If you’re trying to find all of the hidden weapons in RIG Riot, some of them are surprisingly easy to miss. A few are sitting in obvious areas, while others are tucked underneath platforms, behind pillars, or in places you probably wouldn’t think to check during a normal run.
In this guide, I’ll show you where to find every hidden weapon in RIG Riot and explain the easiest way to reach each one. I’ll also mention which weapon and achievement you unlock when you collect each hidden weapon, so you can use this as a complete checklist.
RIG Riot Hidden Weapon Locations and How to Find
Most of these weapons are hidden across the tutorial, arena maps, and later areas such as The Wastes, The Facility, The Prison, The Guts, and The Nexus. Some locations are much easier to explain once you know what landmark to look for, so I’ll point those out as well.
There From The Start
Achievement: Straight and Narrow
This is probably one of the easiest hidden weapons to find because it’s located in the tutorial.
Near the end of the tutorial level, head toward the back-right corner.
Look underneath the platform and you’ll find the weapon sitting on the ground.
Pick it up and you’ll unlock Straight and Narrow.
You don’t really need to go out of your way for this one. If you’re paying attention during the tutorial, there’s a good chance you’ll find it naturally.
Down Range
Achievement: Sunshower
The next hidden weapon is located in the firing range.
Despite the name of the achievement clue, the weapon is actually much higher than you might expect.
Look above the extraction pad, near the top of the skybox.
You’ll need to use your boosters to reach it, so make sure you have enough movement capability before trying to grab it.
Once you reach the weapon and collect it, you’ll unlock Sunshower.
This one can be particularly easy to miss because most players naturally keep their attention on the firing range rather than looking high above it.
We Got Encaged!
Achievement: Propagator
This hidden weapon is located in the arena map Bandit Cage Match.
When you spawn into the map, immediately take a hard right.
Continue toward the opposite end of the area and look underneath a collapsed building.
The weapon is hidden underneath it.
Once you collect it, you’ll unlock the Propagator.
The location isn’t too difficult once you know which direction to go, so the main trick is simply remembering to check beneath the collapsed structure.
Cut Corner
Achievement: Rainstorm
This weapon can be found in the Corporate Crossroads arena.
Head toward the back corner of the map.
You’ll find the weapon sitting at ground level, making this one much easier to collect than some of the other hidden weapons.
You don’t need any complicated movement or special route.
Simply make your way toward the back corner, find the weapon and pick it up.
Doing so unlocks Rainstorm.
Box Cutter
Achievement: Folding Blade
The final hidden weapon found in the arena maps is located in the militia holding cell.
When you spawn into the map, use your spawn position as your reference point.
Look toward the back-right pillar.
The weapon is hidden behind it.
This is one of those weapons you might actually find by accident because the location isn’t particularly complicated. If you’re exploring the holding cell, make sure you check behind the pillars.
Collecting it unlocks the folding blade.
Precarious Situation
Achievement: KRS Plasma Cannon
Now we’re moving into the larger areas of the game.
Head to The Wastes.
From your spawn point, look toward the opposite side of the area.
You’ll find a small village section with approximately four explosive barrels toward the back.
The hidden weapon is sitting behind those barrels.
Be careful when approaching because, as you can probably imagine, standing around explosive barrels isn’t exactly the safest place to search for loot.
Collect the weapon to unlock the KRS Plasma Cannon.
Fans of Armored Core may recognize this weapon immediately.
For Safekeeping
Achievement: Energy Revolver
This weapon is hidden inside The Facility.
From your spawn point, move in the opposite direction along the ground level.
You’ll eventually find a long road with a ramp at both ends.
The weapon isn’t sitting directly on the road.
Instead, look underneath the far side of the road, on the side opposite the wall.
The weapon is hidden underneath there.
This one took me a little longer to find because it’s very easy to run past the road without looking underneath it.
Once you pick it up, you’ll unlock the Energy Revolver.
Lost In Transit
Achievement: Armageddon
This hidden weapon can be found in The Prison.
This one is a little harder to describe because there are cargo boxes all over the area.
Start by looking around the section where you initially spawn. Specifically, you want to stay within the lowest circular section of the map.
Look for a large pile of cargo boxes.
The important landmark is a group with three stacks of long crates positioned in front of it.
Once you’ve found the correct pile, look on top of the cargo boxes.
The hidden weapon is sitting there.
Grab it to unlock Armageddon.
If you’re struggling with this one, don’t just search every cargo box you see. Use the three stacks of long crates as your main landmark.
Busted
Achievement: Mega Launcher
The next weapon is in The Guts.
This one becomes quite easy once you know exactly which platform to check.
Look for the second-lowest platform in the area.
You’ll find a large pillar there.
The weapon is hidden directly behind that pillar on a small platform.
From a distance, the weapon can look like a tiny black dot, so it can be easy to overlook while moving through the area.
Get behind the pillar, pick it up, and you’ll unlock the Mega Launcher.
Overwhelming Power
Achievement: Siege Cannon
This is the final hidden weapon and arguably one of the more complicated ones to obtain.
It is located in The Nexus.
There is a slight story spoiler here, so if you haven’t finished the game yet, keep that in mind.
How to Get the Siege Cannon
First, go through The Nexus normally.
Complete all of the major objectives in the area.
After you’ve finished those objectives, make your way to the center of the map.
There, you’ll need to complete the boss fight.
Once you’ve defeated the boss and watched the following sequence, the weapon will drop from the small rig that you fight.
Simply pick it up after it drops.
This unlocks the Siege Cannon.
Unlike some of the earlier hidden weapons, you can’t simply rush into The Nexus and grab this one immediately. You need to progress through the area’s objectives and complete the boss encounter first.
