Send Those Slimy Mongrels a Message

You’re definitely not going to put much of a dent in that alien army without a serious arsenal of weapons. Many of these alien invasion games start you off with a simple pistol or even a melee weapon, so you will have to be really tough to work your way up to the big guns. Once you start bagging some baddies, cashing in coins and upgrading your weapons in these alien shooter games, you’ll be packing some serious heat! Sure, a pistol or machine gun might be great for taking out two or three enemies in a few seconds, but we’ve got something much more powerful for you. How about a rocket launcher and some grenades? Now we’re getting somewhere. Especially in alien survival games, you will want to build up your arsenal, but be smart with your ammunition. Wait for those ugly invaders to cluster together, and then BLAM! Watch those bits fly!

Set Up Your Defenses

Even with the most high-powered weapons, it’s always a smart idea to put as much between you and those aliens as you can. In a lot of these alien attack games, you can find ways to protect yourself. Find a shield, grab extra health, or even get some body armor for a little extra padding. You can also put obstacles in their way to slow them down or do a little extra damage. In alien space games, you can usually find powerups that will protect your ship for a short amount of time as you rain lasers across the cold vacuum of space at one enemy spaceship after another. However you protect yourself in these alien fighting games, it is a great way to stay alive for much longer. If you can balance a great offense (those awesome weapons we talked about) with a smart defense, you might just survive.

Choose from the Most Thrilling Alien Games Online

If anything, we can promise that you won’t have a dull moment in any of these alien fighting games. There will be no tricky problems or clues – just death and destruction for anyone who decides to mess with you and your planet. The one thing we can do to add variety, though, is to change the environment, the weaponry and the enemies. If you like to just strap a huge gun onto your back and charge into enemy territory like a madman, then we have plenty of options for you. If you prefer to swat those alien missiles out of the sky using a cool anti-ballistic laser, then we’ve got you covered also. It’s all here, just take a look!

They’ll Regret Coming to Earth

They’ve watched us from their fleet of spaceships for years, and they’ve finally decided to conquer our planet. Little did these ugly invaders know what was waiting for them as soon as they set their feet on the ground – a lone hero with a gun. At first, they laughed at how small the resistance was. A few hours later, with hundreds of their soldiers piled high, they weren’t so cocky. We love the one-man-army style when it comes to alien survival games, so we’ve got plenty of opportunities for you to take them on by yourself. Load up Aliens Attack, one of our favorites, to see what we mean. You might as well tape that trigger down, because you’ve got a lot of house cleaning to do!

Missiles Away!


Even more deadly than the legions of alien ground troops are their rockets and lasers, which target the planet’s most valuable structures from above. In Planet Defense, one of our most highly acclaimed alien games online, you are given the huge responsibility of defending these military bases with anti-ballistic missiles fired from a single turret. Needless to say, every miss could cost you dearly. The fate of the world rests in your trigger finger, so keep your eyes peeled and swat down those rockets!
