The Classic
There is a way to be able to unlock the Classic PPSH in each WWII map by doing small side quests.
The video below by Mr.L explains how to do this on all WWII maps.
Power/Pack a Punch
The Power on the map is turned on in multiple areas. The first area is in the 'Village Center' which the player will need to turn on 3 valves in order to power up a generator which powers up the Pilot Light trap. The player will then need to activate the trap and jump into the hole it creates. They then need to run up the tunnel and interact with another generator in order to power up the doors to be able to purchase them.
The other power is to open the door to the 'Salt Mines'. To do this the player must activate 2 power box switches in the 'Morgue' and the 'Laboratories' in under a minuet. If done fast enough the player will then be able to purchase the door to the 'Salt Mines'.
Pack a Punch can be activated by first of all heading to the 'Sewer' room and interacting with a red button near the MP40 wallbuy. Each time the player interacts with a button it will start to lift up the cage on top of the Pack a Punch. To find the other buttons the player will need to head to 'Command Room', 'Laboratories' and the 'Tower' and use the disposable tubes. Once they use a tube they shall land in a gated area in the 'Sewers' where they can interact with a red button to then remove the cage around the Pack a Punch. Once all 4 buttons are pressed the player will have access to Pack a Punch for the rest of the game.
The video below by JokerAlex 21 explains how to activate the Power on the map and how to access the Pack a Punch.
Tesla Gun
The player must have turned on the Power to the 'Salt Mine' door in order to begin the Tesla Gun upgrade process.
In the 'Command Room' the player will need to interact with the crank to open up the hatch that is located next to the 'Salt Mine' door. After this the player will need to head down to the bottom of the 'Salt Mines' into the 'Emperor's Chamber' and interact with the device in the middle back of the room to power it up. Once done the player will then need to get zombie kills inside of the red circle. Once enough zombies are killed the room will light up bright red and orange.
The player will then need to head back up to the 'Command Room' and interact with the red button next to the crafting table for the Tesla Guns. This will then sent a device on a set path to obtain a part for the Tesla Gun. The device will have a red circle around it that the player must kill zombies in to be able to keep it powered up. It will eventually reach the 'Laboratories' and start to make a part of the Tesla Gun. Once its done the player will need to pick the part up and the device will return to the 'Command Room'. The device will then go the opposite direction this time to the 'Morgue'. The player will need to repeat the same process as before and once the other Tesla Gun part is made pick it up.
The player will then need to head back to the 'Command Room' and kill the Brenner that spawns in. Once done head up to the Tesla Gun crafting table and craft the Tesla Gun.

The player then needs to interact with the Uberschnalle again which will start a lock down where the player must protect the Uberschnalle for around a minuet or so. Once the lock down is over the player then needs to pick up the upgraded Tesla Gun part from the middle of the tank.
