Hello there fellow gamers!
A game called Astro Duel 2 is free to keep forever.
As long as you claim a copy before 16:00 UTC on the 14th March.
Astro Duel 2 is a sci-fi combat game combining top-down space dog fights with up-close platforming action. Whether versus or co-op, battle through space and on foot at the same time! Strike within the fully-destructible arenas or just nuke ‘em from orbit.
Have fun! 
Next week, Deus Ex: Mankind Divided will be free. So will The Bridge.
