Exotrex2: The Scientific Space Adventure Game Continues!

Exotrex 2 is a beautifully rendered, STEM focused game that will challenge and engage your 8th – 10th grade science students.

The Story of ExoTrex 2 

Life on Earth is no longer sustainable. Due to this fact, you must venture into space to find a new home for humanity. 

Gameplay begins as you arrive at the Mars orbital station, ready to put the astronaut training from Exotrex 1 into practice. From the start, you must explore an in-depth solar system map to learn about the planets, moons and asteroids as well as their relative distances from each other.  Then, you must choose between three missions- exploring Mercury, Venus and Titan. Only by demonstrate your resourcefulness will you be able to find that new home for humanity. Now’s the best time to start the second phase of your scientific space adventure!


While completing these missions, students will start by balancing speed, thrust, and acceleration while navigating gravitational fields to successfully land rovers on their chosen planet or moon.  They will remotely navigate their rovers to collect ground and atmospheric samples and later analyze them for their chemical compositions.  Students will also learn about the planetary characteristics of each destination and take observational notes. 

No space mission would be complete without a life-threatening emergency and Exotrex2 delivers!  Students will be challenged to reboot their life-support systems while engaging with thermal, kinetic and electrical energies in a race against time!

The ExoTrex™ game has a series of fun facts on chemistry and planetary science presented by the character Dr. Burke during the game play.  These fun facts with the voice over by Dr. Hakeem Oluseyi are a great way to engage the classroom on a daily basis when preparing to use the game or in your lesson planning.  You can view them all on our YouTube Fun Facts Playlist
