Browser Platform Game for 1 & 2 Players - Interplanetary 3

Rating: 8/10 - 86 votes

Play a teamwork-based, platform adventure game where your task is to guide a courageous astronaut duo through a series of increasingly-difficult, ledge-based levels. Interplanetary 3 is an interactive, escape-the-level brain teaser game for one or two players where you must safely maneuver a ‘little and large’ astronaut pair through 20 ledge and obstacle-filled environments. Completing the game is a tricky task for two friends or family members, and a highly-challenging mission for one player alone controlling both characters simultaneously!

Skills required: As this a fun mashup game combining problem-solving puzzle elements and Mario-style 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.

How to Play: A Flash-based, one or two player platform adventure game for notebook, laptop and desktop PC / Mac (with certain browsers). In each of the 20 increasingly-difficult levels, your task is to guide both astronauts to the pyramid-shaped grey spaceship. However, this spaceship only becomes a viable ‘exit portal’ when you have collected all of the special gemstones dotted around the level. The number of gemstones that must be collected is displayed at the bottom of the play area.

Control the ‘Large’ astronaut using the WASD Keys and the ‘Little’ astronaut with the Arrow Keys on your computer keyboard. Large can extinguish fires by simply stepping on them, while Little can raise protective bridges over pools of lava. Pressing the K Key causes Little to fire laser beams. You can also use either astronaut as a ‘stepping stone’ where one character hops on top of the other in order to reach higher ledges.

If either astronaut comes into contact with harmful fire or alien bad guys, you must replay the level. In later levels, meteor showers arrive at irregular intervals (These meteor showers are preceded by warnings). If either astronaut is caught out in the open during a meteor shower, you must re-play the level. Make sure both are standing in gold-colored ‘safe zones’ during these meteor showers to keep them safe. Constantly replenish each astronaut's oxygen levels by collecting blue oxygen tanks. Enjoy the challenge!
