How to play

In Geo War, there are full of ships as this consists of 10 official missions and 2 training missions, each mission will take place in an area and make your ship evolves as you complete missions. The game is to fight with your ship against anyone who stands in your way so he can save humanity.

At the beginning of the mission take a single ship loaded with weapons base, but over the course of the different areas you can get power ups to improve your fire and bombs.

It contains two different characters, each with its own characteristics of attack (Progress for each character is stored seperately).

There are multiple levels of evolution in this game. You will see it in the story and through some funny naming references, but also throughout the missions you will see you ship & capabilities evolve.

In intense battles you will see the explosions evolve into massive blasts. Once you have upgraded your ship by playing through the missions, the upgrades persist with you - so you can go back and play Mission one with all the new capabilities. So in this way, the game really evolves to allow you to max out scores.
