Laboratory

 is one of the Locations in the game The Metronomicon.

Summary
Upon buying the 4th and final school upgrade, the Workshop will be replaced with Sara's Laboratory. From there, players can spend their Street Creds to buy the ultimate weapons - 8 items specifically tailor-made for each of the 8 characters.

Buying 3 out of the 8 weapons will unlock the fifth and last Team Attack, Critastrophe. It does not matter which 3 you buy, so you can buy the 3 cheapest in order to quickly unlock the team attack.

Trivia
Chundersaurus, the first boss of The Weaponographist, can be seen on top of a filing cabinet.
