Bethesda announced it's re-releasing Quake 4 later this June for a discounted price.
The game goes on sale for $19.99 on June 19 in North America and Europe. It's already available on Steam.
The original game was first released in 2005 through publisher Activision. It was developed by Raven Software in collaboration with id Software. Bethesda later acquired the rights to the game when parent company Zenimax Media purchased id Software.
