In a surprising turn for an FPS title, Guerrilla Games has announced that the upcoming Killzone Shadow Fall will lack any kind of experienced based multiplayer progression. In its place will be a challenge based system where completing certain sub-objectives will allow for points to be added to a player’s rank. This will in turn reward weapon attachments, ability enhancements and similar upgrades normally seen in these games.
Many of these challenges will vary in difficulty and the specific circumstances required to achieve them. The two examples the developer cited were “Destroy 1 Turret” for an easy, straight forwards challenge, with a more difficult task being “Kill 1 enemy player with Laser Tripmine while they are carrying a Beacon.” It was not made clear if these were actual examples from Shadow Fall or not.
