The game is playable in browser on Poki.com and during 2021 we will launch on mobile app stores. Stay tuned for news about releases.

MiniPool.io

Gunfight.io

Gunfight.io is an intense multiplayer game with pixel graphics. In the game, you and your team must eliminate the other team in a gunfight. Join either as a counter-terrorist or as a terrorist. The first team to accumulate 25 kills wins the battle. Crouch behind an object to protect yourself from the enemy's fire. To shoot, you need to enter scope mode; this mode has very limited visibility and you will have to stand up (which means your body is exposed and vulnerable to an attack). In certain maps, you can pick up a rocket and use it to deal high damage. Back up other team members to ensure victory. Good luck!
