GunGame.io

GunGame.io is a 2D shooter where your weapon upgrades with each kill — the classic Counter-Strike gun game mode in IO format. Start with a pistol, end with a knife, race through the weapon tiers.

How to Play

Kill opponents to advance through a fixed sequence of weapons. Each kill upgrades you to the next weapon — from pistols through SMGs, rifles, and finally a knife. First to complete the sequence with a knife kill wins.

Controls

• WASD — move
• Mouse — aim
• Left click — fire
• R — reload

Tips

• Early weapons are easiest to kill with — build momentum
• Late-tier weapons can be tricky — snipers require skill
• The knife is hardest — you need to get close
• Don't suicide — losing kills demotes your weapon
• Anticipate weapon changes — play appropriately
