Ends April 02. Every two weeks Epic gives away 2 to 3 games away for free with no strings attached. They are doing it in an effort to build there userbase, which should lead to future purchases.
Right now there is WWZ plus two smaller independent games, which I usually DL simply because they are free and they could come in handy one day if my kid ever decides she wants to play too since at least some of them are kid appropriate.
So far I have 19 games in my library for which I have paid a total of $2 for.
Some games I picked up for free are:
Borderlands 3 (Free with a hardware purchase)
The Outer Worlds (Fee with a hardware purchase)
Watch Dogs (I will make you cry in free roam)
Kingdome come deliverance (Loving it)
Assasin's Creed: Syndicate
Off World Trading Company
And some other smaller titles.
You can pick up a major AAA every once in a while. Just thought I would share the info in case someone isn't aware.
My gaming tag on steam and epic is Dashabox if anyone wants to add me.
