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.

Space conquerors sign up here! Eridani is an epic and in-depth intergalactic battle strategy and resource management game for older kids where your brilliance is needed to lead a futuristic conquest to find a ‘new Earth’ for the human race. In a series of tactical space-based battles, you have to slowly but surely dominate a faraway galaxy using a combination of savvy battle strategy, ultramodern technology, swift war ships, good research, and more. The year is 3012, and after narrowly surviving a giant asteroid, the Earth was catastrophically spun off of its axis. With the planet hurtling toward the sun, the decision has been made by the global government to find a new planet. Fortunately, one was spotted near the Epsilon Erdani star that seems to have an atmosphere very much like earth's. However, this ‘New Earth’ is already inhabited, and the current occupiers aren’t going to give it up to invaders without a fight to the end!

Fans of tower defense-style tactical play as well as all-out battle challenges should enjoy this detailed, innovative, and highly-stimulating real-time strategy (RTS) game which centers around your decision-making process under the extreme pressure of a full-on battle. You are in control of an entire fleet of futuristic warships, battle stations, and resource mining machines, and you must decide the correct manner in which to assemble a workable force that has a reasonable chance of success against your "alien" enemies (and that is how they view you too). The human race's future is at stake! Have you got the tactical know-how, determination and stamina to pull us through? To say we’re counting on you, is an understatement!

If you make contact with any obstacle, you lose health from your ‘Hull’ strength. If your ‘Hull’ bar reaches zero, your rocket-launching adventure comes crashing back down to earth!

Your strategic decision making comes into play as you have to carefully choose which upgrades to purchase to improve your chances of blasting higher and higher. If you’ve got quick reactions and nifty fingers, you won’t need NASA this time round – you can reach outer space all by yourself! Ready for blast off, Master Rocket Maker? 3, 2, 1 Lift-Off.
