Free online arcade games will rarely give you for free games like Spaceship on the run. You better grab it before they change their minds.
Spaceship on the run is an addicting little game, where you operate a rocket, which needs to collect as many precious space eggs as possible. While you collect those valuable points, Martians will try to shoot out of their territory. Yes, you are on the enemy field and your playing skills are the only ones that can make you win or loose in a snap.
Get it now, it is free, it is fun, but it will not be there for ever.
