In Metalstorm, the basic controls include using the joystick to move your character and buttons for shooting and deploying special abilities. Familiarize yourself with the layout in the settings menu for optimal gameplay.

To upgrade weapons, collect in-game currency during missions. Access the upgrade menu from the main screen, select your weapon, and choose the desired upgrade. Each upgrade increases damage, fire rate, or range.

Completing missions in Metalstorm is crucial as it unlocks new levels, provides currency for upgrades, and earns experience points. These factors enhance your character’s abilities and weaponry, making it vital for progression.

Special abilities can turn the tide of a battle. To use them effectively: 1. Wait for the ability cooldown to complete. 2. Assess your surroundings for optimal timing. 3. Target multiple enemies or high-value targets. 4. Combine abilities with teammates for strategic advantages.

In multiplayer matches, teamwork is essential. Communicate with teammates, coordinate attacks, and cover each other. Also, switch between offensive and defensive strategies based on the situation, and prioritize high-value targets for victory.
