Backup Vent Skipping

Due to the way the game handles objects, Player and Player-in-vent are two separate entities, which we can abuse for skipping the "Kill backup" objective.

When the enemies arrive, they are given Player's current coordinates to move forward to. When we are in a vent, however, the Player object is nonexistent and, as such, the backup is given coordinates to a nonexistent entity. As a failsafe, instead of crashing, the game skips the objective and lets us avoid wasting time on killing more undead.

The Souls Guide

All achievements give you 20 souls, except for Death, Famine, War and Conquest (50 souls).

For completing a level you are given: 10 souls for Zombie Kingz levels, 15 for 1000 Year Royals levels and 20 for The Dredged & Demon ones.

Weapon Duping

1) Choose a primary of your liking via the car (grab a secondary as well)
2) Switch to your secondary
3) Unequip your secondary via car
4) Your primary will now appear in your secondary slot, resulting in having 2 primaries at once.

Additionally, there is no need to equip your secondary once again if you want to dupe another weapon. You can simply switch to the weapon in your secondary slot and choose another primary via car. This also means that you can have combos, such as Revenant + D&T, etc. etc.
