TL:DR fill out the worksheet from the pack's files, and get in and out of the Backrooms to win!! (woah)

Modpack info:

This is a kitchen-sink pack that uses Meulti's Backrooms mod in order to allow you to larp as an IRS agent. You get to use a bunch of gadgets from Superb Warfare and its add-on MCSP. The actual IRS uniforms are from LesRaisins Armor.

Backstory:

The Backrooms have been, for quite some time, the epicenter of otherwordly cabals, unfathomably grotesque and vile beings, and, worst of all, violations of 26 U.S. Code Subtitle C Chapter 25. For this reason, the Criminal Investigation (CI) branch of the Internal Revenue Service (IRS) has made the excutive decision to start a case against the denises that inhabit the Backrooms.

You, as a Special Agent of the IRS's CI body, have a simple task to accomplish, document as many undisclosed goods, private records and/or anything that could be framed as tax evasion or fiscal fraud, and which could lead to a judicial trial. To this end, you've been issued a worksheet (found in the modpack's main folder) to fill out and submit once you're out of the property. You've also been given standard issue equipment and more than plentiful supplies, make sure you do not waste tax-payer money by misuing them.

Rules of engagement are in effect during the course of the whole operation, do not shoot anything not hostile.
