Metal Soldier Squad is a classic side-scrolling shooter game available on the iPhone platform. Developed by Vu Khac Hoan, this game offers challenging gameplay and a variety of weapons. As the player, your mission is to destroy the Red Falcon, an alien invader along with its minions who have invaded the earth.

In Metal Soldier Squad, you'll face off against the entire alien army, armed with only five lives and the ability to take one hit before dying. The controls are simple, with A for jumping, B for shooting (with auto fire), and the control pad for movement, crouching, and aiming your weapon. To shoot straight down, you'll need to jump up with A and then hold down while pressing B.

Throughout the game, you can acquire more powerful weapons by shooting flying capsules, upgrade boxes, or brownish-red colored soldiers in the bases. These weapons include a rapid-fire rifle, a machine gun with auto fire, a fireball weapon that hits enemies that are crouched, a laser that strikes hard and fast, a spread gun that covers a wide range, a barrier that provides temporary invincibility, and a health item that adds an extra life. There's even a kill item that eliminates all enemies in the current view.

Metal Soldier Squad is a challenging side-scrolling shooter with a variety of weapons and intense gameplay. Can you defeat the Red Falcon and save the earth from the alien invasion?
