Get Secret Mission Boss Arena Training Area in Roblox Rivals

How to Get to the Secret Mission Boss Arena Training Area in Roblox Rivals Season 3 2026.

Learn how to get to the secret mission boss arena training area in Roblox Rivals. This hidden area lets you practice boss fights without starting the whole mission over each time.

The boss arena training area is hidden behind a door that only opens when you shoot the 45 degree targets in the right way. You have to shoot 10 targets. When you find and shoot the last 3 targets, you will hear a noise after each one.

Let me show you exactly what to look for and how to do it.

What the Targets Look Like

The regular targets look like a plus sign (+). Those are not the ones you want.

The special targets are rotated at a 45 degree angle and look like an X. Those are the ones you need to shoot.

Here is a quick way to remember it:

• Plus sign (+) = do not shoot
• X shape (X) = shoot these

Step-by-Step: How to Open the Secret Boss Door

This is how to open the secret boss door in Roblox Rivals. It is not a glitch. It is a designed puzzle. If you have been trying for hours, just follow these steps.

Here are the steps:

• Look for targets shaped like an X (not a plus sign)
• Shoot 10 of these X-shaped targets in total
• When you find the last 3 targets, you will hear a noise after shooting each one
• That noise means you are close to opening the door
• After you shoot all 10 targets, the secret door will open

A few important things to know:

• When you shoot an X target, it disappears but then shows up again in a different place after a few seconds
• You cannot just shoot the same target over and over. You have to find different ones
• Keep moving around to find all 10. They are scattered in the area

What Happens After You Open the Door

Once you shoot all 10 targets correctly, the door opens and you can enter the boss arena training area.

Inside, you will find the Shady Chicken. When you interact with it, you get two options:

• Go into the boss arena with the Nosniy Bot
• Go into the boss arena with the Sensei Bot

Both bosses are very hard to beat. But that is why this training area is so useful. You can practice without starting the full mission over each time.

How the Training Area Works

Once you open the portal to the secret area, you can keep accessing it until you leave the server. Nobody else can see this area. It is only for players who shot the X targets.

When you talk to the Shady Chicken and choose a boss, you get to pick your weapons. But here is an important thing to know:

The weapons you choose cannot be any weapons from outside. You can only pick from the weapons the game allows for each boss fight. Your regular weapons from outside the training area do not matter.

For example, if you choose the Sensei Bot, the bazooka (RPG) is a good choice because it makes a lot of damage.

Best Weapon Tip for the Target Puzzle

Learn how to get consistent access to the secret mission boss arena training area just by aiming at those angled X targets. I also show you the best weapon to use for shot placement in case your bullets are not registering.

If your bullets are not hitting the X targets properly, try using a sniper rifle. The precision helps a lot with those 45 degree angled shots.

What to Know About the Boss Fights

When you enter a boss fight from the training area:

• If you get killed, it is finished. You have to start from the beginning
• But you can always go back to the training area and start again
• You do not have to redo the target puzzle each time as long as you stay on the same server

The boss fights are very difficult, but they are not impossible. Practice in the training area as much as you need.

Final Reminder

The whole secret area is only for players who shoot the 10 X-shaped targets. Regular plus sign targets do nothing. Focus on finding those rotated 45 degree targets that look like an X, listen for the noise on the last 3, and the door will open.
