Alien Outbreak 2: Invasion/Bonuses and Weapons

Power-Ups and Primary Weapon

The game features several Power-Ups, all of which help you in different ways. They are dropped from the destroyed enemies from time to time. Only one duration-based Power-Up can be active at a time

• Extra Points - Extra Points will just give you extra bonus points when you collect it. This Power-Up is frequent, so pick it whenever you can for getting to hall of fame.
• Extra Energy - Extra Energy will raise your ship energy, causing the indicator bar to go up. If the indicator bar reaches the top, you will get an extra life and your primary weapon will gain more firepower. Extra Energy will be very frequent Power-Up dropped from the destroyed enemies.
• Double Damage - Double Damage will double the damage the bullets your primary weapon deal to enemies whenever they hit them for 15 seconds. Double Damage is a very important Power-Up for dealing with bosses and strong enemies that come in big numbers.
• Invulnerability - Invulnerability will cover your ship in an energy sphere that will make it temporarily invulnerable to enemy bullets for 15 seconds. Invulnerability is a must-have when facing enemies capable either of performing rapid fire, or firing at your current location, or both at once.
• Double Rate of Fire - Double Rate of Fire will double the rate of fire of your ship for 15 seconds. Double Rate of Fire will allow you to fire much faster and finish off enemies more swiftly and efficiently.
• Time Deceleration - Time Deceleration will cause the flow of time in the game to be much slower, which will greatly decrease the speed of enemies and their bullets, thus giving you more time to react for 15 seconds. Time Deceleration Power-Up can be a real life-saver in critical emergencies like being swarmed by enemies and their bullets.
• Invisibility - Invisibility will make your ship invisible to the enemy ships so that they can't provide accurate fire for 15 seconds. Invisibility is very good Power-Up against enemies that fire at your current location, but it is less effective against enemies capable of firing in spirals, and it won't work against enemies who only fire straight-forward. Also be mindful that Invisibility is a double-edged Power-Up because while it can make enemies fire inaccurately, this can also allow them to block your path when trying to dodge other bullets and enemies alike.

Extra Weapons

Your ship can carry up to 3 extra weapons which can deal great damage to multiple enemies at once. Limit to how much supplies of extra weapons your ship can carry is 10. Only one type of extra weapon can be present at a time.

• Rocket - Rocket allows you to fire a pair of big rockets that can destroy any enemy in a single shot, except the Bosses. You get five ammo clips for Rocket when you collect it.
• Lightning - Lightning allows you to fire a lightning beam that can destroy any enemy in a single shot, except the Bosses. Lightning is very good for taking out enemies grouped in a column. You get two ammo clips for Lightning when you collect it.
• Bomb - Bomb allows you to fire a bomb which when close to enemies, it will explode into smaller fragments of itself that will smash everything on their way and destroy any enemy in a single shot, except the Bosses. You get three ammo clips for Bomb when you collect it.
