Interplanetary is a fun and interactive, teamwork-based, platform adventure game where you must guide two brave astronauts through a series of dangerous ledge and obstacle-filled levels on dangerous planets while avoiding aliens. The ‘little and large’ combo must collect all of the green gems in each level, and then make their way to the spaceship in order to progress. But there's no time to hang around – Oxygen is scarce on these interplanetary levels, and the clock is ticking!

Reasons to play this cool, platform-based skill game: Unleash the power of teamwork and combination play as you utilize the individual attributes of both characters to work toward the common goal of escape in each level. Play the game as a solo mission by controlling both astronauts simultaneously, or enlist the help of a friend, classmate or family member to control one of the characters as part of a dynamic, platform-conquering duo!

Strategy to win: As well as combining the jumping skill of the ‘little’ character with the fire-quenching power of the ‘big’ character, you must also use fast reactions, reflexes, and good keyboard control skills. Multitasking skills also come into play – especially if you are playing the game on your own, and controlling both characters. Most of all – you must think of the astronaut duo as a "team", as without the help of one another, they're going nowhere!

Blast your space invader enemies and defeat the Big Boss! A-Blast Liberation is a straight-forward, space invaders-style shooting action game and mouse control challenge where you must eliminate wave after wave of alien enemy spacecraft while dodging and weaving to avoid missile fire and collisions. Set in a confined, high-intensity, arcade battlefield, you must fend off increasingly-powerful groups of alien fighters (known as the Alien Armada), eventually taking on a Boss character at the end of each level.

Reasons to play this high-octane, space invaders game: Nostalgic fans of 1970s and 80s retro space invader games should enjoy the familiar top-to-bottom game play, while beginner players are also greatly tested. A high difficulty level means this game presents a real challenge. You need to be completely ‘in the zone’ to succeed!

Strategy to win: To go deep into this all-action arcade game, you must exhibit super-fast reactions, excellent hand-eye coordination & mouse control. Decision-making skills are also important – To decide when and where to go on a full-on attack, and when to dodge and let enemy spacecraft pass. 100% Concentration is Key; there is very little room for error, and the aliens just keep on coming!

Orbitron is a fun and addicting, old-school space invaders arcade-style game for kids, teens and family that combines accurate mouse control and reaction skills, tower defense strategy, alien shooting, and a clever use of upgrades and defensive buildings. As Chief Orbit Protector, you are in charge of constructing Tetris block-like defensive walls, eliminating enemies, and keeping your ‘orbit’ (base) safe from wave after wave of enemy attacks.

Reasons to play this fast-paced, online arcade game: Put your reaction speed and strategy skills to the test! Fans of classic space invaders games should enjoy the retro game interface and action here. However, there is also a more modern, futuristic aspect to the game. This is far from a simple, one-dimensional shooting challenge – You also have to construct protective barriers and use good strategy to survive the constant onslaught from enemy alien spacecraft.

Strategy to win: You really need to exhibit fast reactions, sharp hand-eye coordination, and smart observation skills here. Accurate mouse and keyboard control skills are also important. Your decision-making and battle strategy skills need to be hot and ‘on point’! When and where you place defensive measures is the key to you going ‘deep’ into the levels here.

Slow down time, collect powerups, and dodge hazards in a retro-style survival quest! Operation Chaos is an 8-bit, space piloting arcade game where you must use fast mouse control to dodge blocks, enemies and other obstacles in a mad dash to stay alive. In this challenging, vertical scrolling, skill-based game, you can utilize ‘bullet time’ to slow down the action and evade enemies while guiding your spaceship safely to the end of each increasingly-difficult level. Have you got the piloting skills to complete all 10 levels?

Reasons to play: Fans of classic, 1980s-style space invaders games should enjoy the nostalgic action here. However, it's not all about the nostalgia – This game also plays as a stimulating and tricky test and exercise of your reaction skills, concentration, mouse control, determination, and will to win.

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.

Play an arcade space shooter game, and pilot a high-speed mini spacecraft through 30 dangerous maze levels filled with enemy-spawning portals, harmful outer walls, and many more treacherous hindrances! Underrun is a challenging, space invader-style, flying skill and shooting game where you must safely guide a speedy spaceship through narrow mazes toward an Exit Portal. In each of the 30 progressively-tricky levels, you need to dodge and weave around enemy rockets, fire your own missiles back, collect power-ups, and exhibit some top-class piloting skills!

Skills required: This classic-style arcade action game requires excellent timing skills in mastering the keyboard-based control of your spacecraft. Sharp reactions, observation and anticipation skills are vital. Maze puzzle solving determination is also key. The rocket-fueled, momentum-based movement of your spaceship can take some time to get used to, so trial and error and patience definitely play a part in your success.

ReflexION is an intense, neon-themed breakout / ball & paddle game for kids and nostalgic grownups that combines good defensive strategy with fast reactions and mouse control skills. Facing off against missile firing, space invader enemies, you must quickly maneuver your paddle around the game zone in order to protect your core / base area, and deflect and rebound the enemy missiles back at their sources.

Reasons to play this fast-paced, upgrade-based arcade game: Fans of classic retro arcade games such as Pong, Atari Breakout, Arkanoid should enjoy this fun, modernized take on the 1970s & 80s genre. Fans of tower and base defense games should also find ReflexION well worth the time. Each increasingly-challenging level requires 100% concentration, quick reflexes and reaction speed, and coordination skills as you attempt to protect the bottom of the game zone while using rebounded missiles to take out the enemy.

Strategy to win: Good hand-eye coordination and mouse control, and a cool head under pressure is essential as you attempt to use the momentum of your paddle against your enemies. A basic appreciation of angles and trajectory also comes into play as you use the contours of the game screen to perform ‘bank shots’ that take out your enemies from either side. Decision-making strategy is also an interesting factor toward your defense success as you decide which upgrades to select in between each level.

Play a tricky spaceship piloting and shooting arcade game inspired by the 1970s & 80s classic space shooter game ‘Asteroids’ on your mobile phone, tablet, notebook, laptop, or desktop PC! Space Conflict Marathon is a very challenging, 1-level, space invaders-style skill game where you must pilot a spaceship through a really high-intensity field of asteroids and (smaller) meteoroids, destroying as many space rocks as you can with concentrated missile fire. Dodge and weave around the slow-moving asteroids & meteoroids, collect gold discs and score as many points as you can!  

This online, HTML5-based, space invaders / survival skill game should work on iOS and Android devices as well as most web browsers for PC / Mac. Skills required here include focus, alertness, sharp reflexes and anticipation skills, good hand-eye coordination, great determination and will to win!  

Control Tips: For laptop, notebook or desktop players, using the Arrow Keys on your keyboard to control the spaceship and Spacebar to shoot is far easier than using your mouse. For mobile phone & tablet players, the toggle device for moving your ship takes a bit of time to get used to, and you may need a couple of trial runs to get to grips with it. At Learn4Good, we find using your left thumb for steering and right thumb for shooting is easiest. Enjoy this old-school space arcade challenge!
