Epic Games are currently chipping away at Paragon, their upcoming free-to-play third-person MOBA, and it's apparently time to open the floodgates and bring in the masses.
Next weekend (as in, the weekend after the upcoming one), Epic's hosting an open beta freely available to all. It'll run from May 26 to May 30, and all you have to do to join is sign up through the game's website by May 25.
Paragon has been in closed beta for a few months, and those interested can buy access to that for around $20. You'll get a few cosmetic items and similar stuff if you do so. Once the game is in wide release, it'll be free-to-play.
