Solar 2 is a game about astronomy and a sequel to Solar. The game allows the player to control a celestial body and help it to become a planet or a star.

Premise and goals

In the beginning, the player assumes control over a small asteroid. As it grows in size, it becomes a dwarf planet, then a planet that can sustain life. Growing further, it may become a star with its own planetary system, and eventually a black hole.

The ultimate goal of the game is to gather all of the universe's mass into a big crunch. Then it will explode and recreate the space with a Big Bang. However, the player is free to stay at any size instead and not to complete the main goal. There are also optional missions that the player can complete to receive achievements.


The player navigates his or her astronomical object through space, which is a randomly generated open world. To accumulate your object's mass, you have to collide it with smaller objects and absorb their matter. The objects that are larger than yours will only take its mass away if you hit them. Your object can decrease in size, but it cannot downgrade from a planet to asteroid or from a star to a planet. If destroyed, it will respawn with approximately the same mass.

As your planet grows to the life-sustaining size, it will eventually develop a civilization that will launch spaceships. Other planets can have spaceships as well. They will attack other planets and asteroids to destroy them and engage in space wars with your civilization.

Super healthy Casual Game. From the Asterioid to The black Hole and then again from the Front, because the Universe always arises from the front ... So great if you're horny on Play hours, otherwise a nice little Pastime.

Very fluid game. The principle looks a bit like spore. Although the game seems simple, you have to be vigilant when meeting with other systems, so that our planet does not come into contact with others. I recommend it!

Best space game ever < 3 it's still a good big killing. It's very simple, with a minimalist gameplay and yet the game is really subtle and requires strategy. I finally found the best stars war game (note the word game = D)

Cool Game for In Between. Amazingly captivating for the very simple Game Mechanics. The Long-term Motivation is not huge, but that doesn't matter in such a Game. If you are looking for a cool Game for In between, you're certainly in the right place. However, it is advisable to wait for a Steam Sale, as the Normal Price is then clearly too high for what the Game offers.

Seriously, this little game is surprising, for any enthusiast of sideral questions or planetary systems. The music is relaxing, it creates an atmosphere. Physics is well implemented, speed, direction is affected by gravitated and mass. The graphics are simple, but well done. Challenges/missions can be difficult, but there are few impacts that do not succeed. Very good game!

This game is so strange- but really interesting and funy to play... its almost a god sim in his own regard, with an unique setting. The price of 9€ is might a bit to high - but if you can get like 20% or more discount on a sale - its a safe buy to make. I also can image to play this together with a friend (at home) - since it has a lot of possiblitys and allows for quick and long rounds, since each run will be way different. Nothing to complain here. Proud to have it in my library!

Frankly, the system of evolution could have let think of an improvement of the gameplay by adding interesting mechanisms, but they are finally very anectodic and we only capture the objects smaller than us while avoiding the biggest ones all along the game, which loops very quickly to start again, without any novelty. However, the atmosphere of the title could as well as its "Zen" side might interest it, provided not to be afraid of the repetitive.
