Under Defeat - Weapon 'options'

Weapon 'options'

These options, dropped by certain enemies or when you are killed, provide you with 3 possible additional attacks. Any that appear on screen stay on screen until you touch it. Each option icon is color-coded, and change every 5 seconds or so, allowing you to switch between them. Also note that these options won't necessarily target what you're currently firing at, but are smart enough most of the time.

• Vulcan Machine Gun (yellow) - The same as your helicopter's machine gun. It is the weakest in terms of power, but the fastest to recharge.
• Cannon (green) - Eight moderately-powerful salvos are fired one every second, taking out most small and medium tanks and helicopters within a shot or two. Recharge is longer than the vulcan but shorter than the rocket grendade.
• Rocket Grenade (blue) - A single, powerful shot takes out nearly all enemies in the game, as well as doing blast radius damage. This one is especially good for bosses, but its recharge time can be a serious liability.

Each one attacks a certain amount of times, then has to recharge. While the bar is green the option attacks, until it turns entirely red (as the option is attacking). Then, you have to wait for the bar to fade to black. Then, so long as you're not firing your primary weapon, the option bar will turn green again, but if you fire before it fully becomes green again, it resets to black. You can use your selected option as many times as you want, but must allow for the reload time if you want to use it again.
