2009's Borderlands is returning in a new Game of the Year Edition, releasing on April 3rd. It'll be free to all existing owners of Borderlands on Steam, 2K has confirmed, and it'll make a bunch of small but significant tweaks to the game. As well as a minimap in the style of Borderlands 2 which you can switch on or off, the inventory system will be simplified, and you'll automatically pick up items found on the ground like ammo and health. 

There are more fundamental tweaks to the game, too. The game's final boss has been altered for a tougher, more rewarding challenge, and to make it a more "engaging" encounter—we'll have to give that a try before we know exactly what impact that makes.
