How many GB is Alone on Mars?

0.49 GB

That is less than the typical Shooter game, which needs about 8 GB.

Leave at least 6 GB free: games need headroom to unpack updates.

The figure is the storage Steam lists as required for this game, not a measured download.

Alone on Mars is a 2D survival shooter on Mars. An SOS signal was sent from Mars, which was captured by your spacecraft. You decide to change your course and travel to the planet to figure out what happened. Upon arrival, you notice that each space station is home to incomprehensible creatures that appear to have attacked the expeditionary groups and they were forced to send this signal. Did any of them survive? Are there any traces their presence? What does the expeditionary program to visit Mars hide? The gameplay is a platformer with a mixture of sandbox and Tower Defense. Defend the generator, unlock new weapons and solve the riddle of Mars.
