Get 2013's Tomb Raider for PC when you donate $1 or more to charity

Want a copy of 2013's Tomb Raider on PC on the cheap? Donate $1 or more to the GameChanger Charity and Square Enix will hand you a digital copy.

The free copy will be handed out from today through April 5 or until they run out of digital keys. Once the donation goes through, you will be emailed a Steam code.

As part of the 20-year celebration of Tomb Raider, those who donate at least $20 will be entered into a drawing where prizes include a special Crystal Dynamics swag bag. Inside is a collector's edition of Rise of The Tomb Raider, along with special items related to the series.

GameChanger is a non-profit focused on improving the lives of children suffering from life-threatening diseases. It delivers video game gifts to hospitals, and provides financial support to deserving families.
