Missile Strike is a fast-paced, aiming and shooting-based tower defense game set on the Moon! Here, you must quickly and efficiently launch missiles into space in order to destroy the dozens of incoming comets / asteroids that threaten to destroy your space bases. Choose to defend just one base at a time, or test yourself with the more difficult 3-base mode! Showcase your accurate missile-firing talent, and survive for as long as possible!

Skills / strategy required: As head of Anti-Asteroid Firepower, you must combine sharp concentration skills with fast reflexes as you attempt to obliterate as many falling asteroids as possible. A good strategy (especially when you are under pressure) is to ignore asteroids that aren't threatening your bases. Focus on the ones that are careering toward your bases, and take them out as priority targets!

Alien Transporter is a challenging, spaceship flying and taxi driving-based skill game (for one or two players) where you play the role of an outer space cab driver serving a bunch of friendly green alien customers. Using deft keyboard control skills in each level, you must carefully transport the aliens to their desired destinations in an outer space town (ensuring to avoid any unnecessary collisions with obstacles along the way), and then direct your rocket-powered transport spacecraft to an Exit Portal. Collect coins along your routes, and be really careful not to run out of fuel! If you accidentally incur too much collision damage, your transporter explodes!

Skills required: In this fun, tricky, movement-based arcade game, good hand-eye coordination skills are essential as you try to safely maneuver your alien transport spaceship through each confined level. As with driving any vehicle in real-life, practice makes perfect as you exhibit delicate, nimble finger work throughout your taxi journeys. Multitasking skills are important in later levels when two spaceships operate simultaneously.

Outer Space Arkanoid is a fun addictive game in which you must get rid of all the floating bricks in space by bouncing balls off them! You have control of the bounce by moving your board along the bottom of the screen. Use your knowledge of angles to bounce the ball in the direction that you want. Collect power ups from the bricks you destroy and these will help you dispose of the bricks quicker. The faster you get rid of all the bricks the higher your score. Progress onto the next mission once all the bricks are gone! Get your spacesuit ready, we are ready! Are you?

Dispose off all the floating bricks by bouncing the ball off your board and getting the ball to hit the bricks. Each brick requires one hit for it to disappear. This game tests your knowledge of angles of incidence and reflection as this is the method you will need to have any sort of aim in your bounces. Also you must have a fast hand with the mouse to keep up with the balls and the power ups falling down! Good luck!

Alien Gravity - Teach the naughty aliens the art of gravity. Get to the door using nothing but physics as you chop and change the gravity of the moment, floating up and down and essentially walking on walls to avoid the holes and the fire boxes!

The aim of this game is to reach the door at the end. This will progress you onto the next level. The levels get progressively more difficult so it is up to you to make sure you are up to the task! This game will help develop your basic knowledge of gravity and science. Remember, gravity pulls everything to the centre, so on earth (normal mode) it pulls us down towards the centre of the earth, hence why we cant just float off. Flip the gravity in this game and you will be pulled upwards allowing you to walk on the walls up above. This game requires a delicate understanding of when to flip the gravity to best achieve the outcome of reaching the exit door! Enjoy!

Your powerful Cluster Lander craft must flip switches, avoid mine-style baddies, and fly through narrow game environments while avoiding harmful collisions. This is space piloting at its most intricate and testing! Are you up to the task?

Skills required: This tricky space flight arcade game requires a fluid combination of smooth hand-eye coordination skills, really sharp reflexes and anticipation skills, and a willingness to learn from your mistakes (trial and error). The rocket-powered movement of the Cluster Lander requires a very steady hand, and a high level of computer keyboard control.

Play a very challenging, high-intensity, futuristic tower defense game for older kids / teens where you are in charge of defending your server from waves of attacking viruses (geometric shapes). VR Defender Y3K is an innovative, interactive, space-age battle strategy game with cool retro-style graphics where you must defend a super computer's firewall from constant attack by enemy viruses. As Chief Network Security Engineer, you must methodically place virtual turret guns along the network path in order to stop the waves of viruses before they penetrate your firewall.

Background info: The year is 3000, and a hi-tech software company has employed you to defeat the hundreds of viruses that plan to attack their server. However, due to sudden budget cuts, you must raise your own virtual income for further weapons by collecting bounties from each virus that you eliminate.

Reasons to play this cool, strategy-based survival game: Exercise your strategic decision-making skills and tactical battle skills as you carefully and meticulously build turrets in defensively-advantageous positions along the pathway. Experienced fans of tower defense games should enjoy the challenging, fast-paced action here.

Strategy to win: A cool head is important here, as is the leadership skill to see the ‘bigger picture’. Measured, clinical placing of turrets is the best strategy. It's all well and good to have turret guns placed where the enemy first appears but what if they break through your initial defenses? So choose your defense placements wisely!

Skills required: As this a fun mashup game combining problem-solving puzzle elements and action, you must call upon an array of physical and mental attributes to be an ‘Interplanetary’ success. Fast reactions, good hand-eye coordination, anticipation skills, and tactful keyboard control are all very important. Smart analytical thinking skills, problem-solving determination, creative engineering skills, good teamwork and stamina are all called upon here.

Skills required for this tricky arcade game: This challenge requires deft keyboard control, good timing, fast reactions, patience, and the essential willingness to learn from your mistakes. Your ‘lander’ spacecraft moves in a very unusual, gravity-affected manner, and you must show that you are able to adapt to the changing environment in each level if you are determined to succeed.

Spaceship Landing is a challenging arcade-style skill game with a straight-forward concept. You play the role of a spacecraft pilot who must land safely onto all Green platforms that appear in each level (Normally two, and landing on the 1st Green platform frees up the 2nd Green platform by changing its color from Blue to green). However, your spaceship is quite fragile, and you must use the rocket-propelled action of the ship to very deftly land without excessive impact. You must also keep your eye on your fuel gauge, and re-fuel on the Red platforms in order to avoid a loss of control. Playable on mobile phone, tablet, notebook, laptop, or desktop PC, there are 20 progressively-tricky levels which introduce more challenging obstacles and awkward terrain as you progress.

This online, HTML5-based, flying / skill game should work on iOS and Android devices as well as most web browsers for PC / Mac. To play the game with full screen, you may have to turn your device horizontally. Skills required include steady keyboard control or finger tapping, fast reactions, good hand-eye coordination and anticipation skills, and smart decision-making skills.

Controls: For PC / laptop players, use the Arrow Keys on your computer keyboard to control your spaceship. For mobile / tablet players, tap on the blue arrow buttons in the bottom corners of the play area to control the movement of your spacecraft. You have three extra lives for the duration of all 20 levels. If you destroy all of your backup spaceships, it's game over!

Warning: The game starts immediately (the spaceship drops immediately) on loading, so be ready to react the moment you see the spaceship dropping down from the top of the game screen. Completing levels wildly at high speed may not be the best course of action, as you must always be aware of your quite limited fuel stocks.
