This update is based on player feedback and it is the biggest one so far. To celebrate it we are offering a 50% discount for the game. List of changes: [list] [*] Added difficulty level selection. Difficulty level affects the amount of damage you receive and enemies aggressiveness. [*] Added energy shield feature. If you die multiple times in a row it will become possible to activate energy shield which will reduce the amount of damage you receive until you complete your current mission. This feature is not available on the hard difficulty setting. [*] Added visual on screen indication for low armor state. [*] Prices for some vehicles are reduced to make the game feel less restrictive in vehicle choice. [*] Prices for vehicle upgrades are slightly reduced. [*] Missiles will now first attempt to lock onto the target in the crosshair, fallback to automatic target detection if failed. [*] It is now possible to revisit completed missions by picking the Missions option in the main menu. [*] Added main menu background for the lava world that was missing. [*] Small changes and tweaks here and there. [/list]
