Space Armor 2 - a full-fledged shooter in outer setting.
You were sent to the space station to find out the reasons for the ship collided with the star. To find out we have to go through dozens of levels, destroy hundreds of alien monsters and soldiers open multiple weapons and take part in endless battles.
To update the application, install the new version of the application over (without deleting) the old one.
This update will only be possible if the previous version of the application is downloaded from us. Otherwise, there will be a signature conflict and you will see the message "Application not installed".
For what "Signatures" are and what they are for, read here.
