Mirage Firebox Guide: Positions, Angles and How to Clear It

Mirage firebox is a small cubby on the A site where players tuck themselves away. It is a classic hiding spot for a CT who wants to catch attackers off guard. The name comes from how often it is cleared: one molotov or incendiary is usually enough to force anyone out. That makes it a perfect example of a close angle that every T side must deal with.

This guide explains what the spot is for, how to clear it, and when a CT might use it. For the full list of names on the map, see our Mirage callouts guide.

What is Mirage firebox?

Firebox is a small alcove on A that a player can hide behind. It is close to the site rather than far back, so a fight there is at short range. A defender in Firebox is betting that the attackers will walk past without checking.

A, on Mirage, has several close spots like this. Sandwich sits between Stairs and Tetris. Ninja is a small gap between two stacks of boxes. Firebox is another one. If you are not sure exactly where a callout sits, load the map in a private server and walk it with the radar open. Our guide to learning a new map explains how.

Why do Ts molotov Firebox?

Clearing a small cubby by walking into it is risky. The CT knows where you will appear, and you do not know whether they are there. A molotov or incendiary changes that. The fire forces the player to move or take damage, and you never have to take the duel on their terms.

• It is cheap: a molotov costs $400, far less than the rifle you could lose.
• It is reliable: a small space is easy to cover with fire.
• It saves time: you do not need to slow down and check each corner by hand.

Our Molotov guide covers how fire works in CS2, including how smokes put it out.

How do you clear Mirage firebox?

1. Throw fire early. Put the molotov in as your team starts the execute, not after you are on site.
2. Pair it with smokes. A full A take usually blocks CT, Stairs and Jungle at the same time. Our Mirage smokes guide explains those throws.
3. Watch where a player escapes to. A CT forced out of the fire has to move somewhere. Aim at the exits.
4. No molotov? Use a flash. If you have no fire, flash before swinging and enter with a team-mate who can trade.

Common mistakes

• Forgetting the spot entirely and getting shot in the back while planting.
• Throwing the molotov after the site is taken, which wastes it.
• Checking every close corner one at a time while the CT rotation arrives.

When should a CT play Firebox?

A CT can use the spot for a surprise, but it is a gamble. Most T sides will throw fire into it on a proper execute. It works best in specific situations.

• Against a fast rush with no utility. If Ts rush without molotovs, a close spot can catch several players.
• As a one-off. Playing it once in a half can win a round. Playing it every round gets you burned.
• With a team-mate covering. Someone else on site should be ready to trade if you are found.

If you hear a molotov land, do not stay in it. Move out early and play a safer angle. Our Mirage CT positions guide covers safer options on A.

Callout names and their positions were checked on 2 November 2026 against TotalCSGO's Mirage callouts and the Counter-Strike Wiki Mirage page. This guide describes positions and general utility use only. It does not give pixel-perfect lineups. Practise exact throws in a private server with a lineup tool or a trusted video, and check the in-game radar if Valve changes the layout in a future update.
