I can feel it wringing in my ears already. It is calling me already. I see and hear the weekend that’s who! As y’all know, we gather the best sales during our Saturday Surplus Sales posts. But let’s start now!

For this weekend Origin8 has dropped Sentinel Mars Defense to a whopping price of FREE!

As commander of the star ship Sentinel, you head out to Mars only to find out that it has been overrun by aliens. Now it’s your job to defend the colonies tower defense style. Your mission: don’t let the aliens declare “all your base are belong to us!”

You can read our full review or you can simply download the game. It’s your call but download it regardless.
