About this game

The Ministry of Normal has banned all fun science. Its gray army of clerks, inspectors and filing-cabinet tanks is marching on Dr. Max Sprocket's backyard lab. Luckily, Max has gadgets. Lots of gadgets.

BUILD RIDICULOUS GADGETS
• Slime Lobber, Zap-Ray 3000, Reverse Microwave, Punch-o-Matic, Stink-o-Matic, Snooze Projector, Robo-Buddy Factory, Shrink Ray and Hypno-Disco
• Every gadget looks and fights differently as you upgrade it, and each ends in one of two wild specializations, like the Mostly-Harmless Death Ray or the Sock Tornado
• Watch them work: bureaucrats slip, freeze, fall asleep, shrink, walk backwards and even start brawling with each other

MIX LAB REACTIONS
• Slime + Zap = SHORT CIRCUIT
• Frozen + Punch = SHATTER
• Stink + Spark = KA-FOOM!
• Sleeping + Punch = RUDE AWAKENING, and more
• Discover all 8 reactions and write them into your Lab Notebook
• Combos fill the Chaos Flask: unleash a Mega Experiment like the Slime Tsunami, Absolute Zero or the Mega Disco

OUTSMART THE GRAYFORCE
• Armored inspectors, shielded compliance officers, healing HR mediators, flying stamp drones and filing cabinets that burst into angry memos
• Janitors mop up your slime and lawyers shout OBJECTION! to wipe your effects, so plan your combos
• Three bosses, including the dreadfully dull Baron von Boring himself

A HERO WITH A JETPACK
• Move Dr. Max Sprocket around the map, level him up and use Jetpack Stomp and Overclock
• Call in a Rubber Duck Airstrike or drop Emergency Interns when things get messy

LOTS TO DO
• 15 hand-painted, living levels across three worlds, each with lab traps to spring: beehives, fire hydrants, steam manholes, giant rubber stamps and more
• Heroic and Iron challenges, Endless mode and a new Daily Experiment every day
• Research Lab upgrades, 37 achievements and funny comic cutscenes
• Casual, Normal and Veteran difficulty for every level

FAIR AND OFFLINE
• Play 100% offline, anywhere
• Optional cloud backup and a transfer code for moving to a new phone
• Automatic save every wave, so you never lose a run
Build absurd gadgets, freeze bureaucrats and defend your lab. Fully offline TD!
