Metal Soldier Squad

This game is a classic side-scrolling shooter, with a variety of weapons, challenging gameplay, and only 1 player-simultaneous modes. The object of this game is to destroy the Red Falcon, and alien who, along with its minions, has invaded the earth. It's just you against the whole alien army.
The game can be quite a challenge as you die after taking 1 hit, and you only start the game (normally) with 5 lives. The controls for the game are very simple: A - Jump B - Shoot (Auto fire) Control Pad - Move left and right, crouch, aim weapon (Note: To shoot straight down, you must jump up with A, then hold down while pressing B.) Down + A - Drop down a level (if possible) Also, I'm not claiming to call everything by its official name, but hopefully most people won't care. V. Weapons/Items: You start out the game with just a basic single-shot rifle. Fortunately, you can get more powerful weapons (otherwise this game would be extremely difficult). You can only hold down B to fire multiple shots if you have a machine gun or laser, and this is probably the best way to fire these. All bullets strike targets with the same force. The laser strikes with the force of 4 bullets. Upgrades are found by shooting flying capsules, shooting upgrade boxes, or by shooting brownish-red colored soldiers in the bases. R - rapid fire - This only affects the standard rifle and the spread gun. Quite obviously, it just speeds up your bullets. M - machine gun - Has the advantage of auto fire. Just hold down B for a constant stream of bullets. F - fireball - The bullets of this weapon move in a circle about as tall as your player while they travel forward. I don't particularly like it because the bullets travel the slowest of any weapon, but you can hit enemies that are crouched. L - laser - The laser strikes hard and is equivalent to an extremely fast-firing standard rifle. Don't hit B rapidly with this one, or your current laser beam will disappear and a new one will launch. S - spread - This one's my favorite (especially when combined with rapid fire).
Bullets come out diagonally up and down as well as straight ahead, giving you a very wide range. In a 2-player game where both players are armed with rapid spreads, heads will roll. B - barrier - The barrier makes you invincible for a little bit. You'll flash between red and blue. Be very careful with it, though, because it gives you no warning when it's about to end. H - health - Added 1 more life K - kill - Killed all of enemies in the current view
