About the game
In MATH FPS, your trigger finger is only as good as your brain... Solve or Die!
This is a fast-paced arena shooter with one simple rule: solve the math to kill the bot. Forget aiming for the head... you need to aim for the answer.
Every enemy spawns with a math problem floating above it (ie 7 × 6). The correct answer (42) is printed on one specific body part. Shoot the wrong number and the player is dealt damage. Even a perfect headshot is useless if the answer is on the leg.
Think fast. Shoot smart. Survive.
Enemy Types
As the waves progress, you’ll face increasingly dangerous robot enemies designed to test both your reflexes and your mental math:
- Humanoid Drones – Static, slow, or FAST... agile training bots that introduce core mechanics and punish slow thinking.
- Assault Mechs – Heavy, armored enemies that shoot projectiles with multiple answer zones that force rapid decision-making under pressure.
- Swarm Units – Lightweight robots that rush in numbers, overwhelming you with multiple problems at once.
- Elite Spiders– Advanced combat bots with tougher math, faster movement, and relentless attacks that leave no room for hesitation.
Each enemy type changes how you approach the problem.... sometimes precision matters, other times survival means answering fast or clearing space immediately.

What is a Steam gift and how is it different from a key?
A gift is a present our bot sends straight to your Steam account via your profile link: no code to enter, the game appears in your library once you accept the gift. A key is an activation code you enter yourself in the Steam client.
Which gift region should I choose?
The one your Steam account is registered in: Steam will not accept a gift from another region. The region is shown in your Steam account settings under "Store country". "CIS countries" means Belarus, Armenia, Georgia and other CIS countries.
How will I receive the gift?
After payment you enter a link to your Steam profile and the bot sends the gift straight to the account — you only need to accept it in Steam. It usually takes 2–5 minutes, around the clock.
What if the account already has this game?
Steam will not let you accept a gift of a game already in your library — check the library before buying. If it happens, write in the order chat: we will refund you.
