ADDED

• THE CUSTOMIZE BOX: a new machine in the game room - step inside to customize your bubble, crosshair and pets, and to track every achievement.

• Default bubble skins: Orange, Pearl, Steel, Abyss and Marble - each with its own pop burst and pop sound, in every mode.

• Crosshair styles: Sonar, Nacre, Koi, Atom and Static - buy them or earn them with achievements; Nacre, Koi, Atom and Static erupt on a critical hit.

• Achievements: every Steam and in-game achievement in one place, hung as lanterns down an ocean trench - see your progress and claim new ones.

• Pets: Catty now has company - switch on as many pets as you like in the Customize Box.

• The Descent: the more achievements you claim, the deeper your submarine sits in the ocean.

• The lesson monitor now teaches each mechanic with a live animation.

• New achievements: Collector's Edition and The Machine Ate My Money.

CHANGED

• The Exchanger is now a machine you step into

• The Mirror power's card now shows, inside its glass, the power it will copy - in runs, the Bubbleathon and Project Poltergeist.

• The Vampire on Hard: his darkness now clears in 550 Bloody pops.

• Luxury Time and Battery are now free - they no longer need an achievement.

• Blood Shot and Boost Cocktail now have their own Steam achievements - if you already own them, they unlock on your next launch.

• Power Booster now unlocks after 1,000 Booster Bubbles, like Gummy God and Gold Rush - if you already have it, you keep it.

• Flushing the toilet now splashes a little water.

FIXED

• The Bubble Machine's camera no longer stays stuck after a visit.

• The lesson monitor no longer changes channel while you're inside a machine or in another room.

• A rare empty save when the game was started before Steam was ready.
