Weapon Trainer is an engaging mobile game where you play as a character with a backpack. Your task is to fit various uniquely shaped weapons into your backpack, each with different attributes like cooldown time and damage. The goal is to fit as many weapons as possible into the limited space of your backpack.

Once your weapons are arranged, you must face waves of enemies. After each wave, you can reorganize your backpack to better prepare for the next challenge. Additionally, you can collect extra pieces to expand your backpack, allowing you to carry more weapons. Strategize your weapon placement and fight off the enemy waves in Weapon Trainer!
