Maps I've made. Most are custom game modes or Raid (classic briefase).

Classic game mode: Raid
This is a normal briefcase + hack mission, like cliffside, except, it's incredibly large and has a lot of player freedom, and many custom features:

• Intruders pick one "specialist" which is like a perk for your team -- Disguise yourself in guard uniforms, buy better guns, hire a hacker, a wheelman, an explosive expert or a sniper team...
  
• The building itself has many built-in security features -- laser motion sensors, shootable cameras, interactive computers, alarms.
  
• The "server room" briefcase is protected by a security coded door, and if you trip the laser-alarm, the room will quickly fill with poison gas, forcing you to quickly grab the briefcase and leave before choking. The laser alarm can be disabled from the main security room.
  
• The "executive suite" briefcase is protected by a laser-alarm, which sounds an alarm that can be heard over almost the entire level. The laser alarm can be disabled from the main security room.
  
• A complex system of vents allows several security systems to be bypassed, however, some may require teamwork (such as riding on top of the elevators while your team-mates move them from floor to floor).
  
• The city block surrounding the building is completely traversable, 360º. Climb on rooftops to escape or ambush. Enter the sewerage system via the subway train platform to sneak into the underground car-park.

Classic game mode: Raid (mostly)
The tables are turned as the guards are trying to re-capture their stolen briefcase!
The intruding-guards arrive at the intruder-safehouse first, but must defend it until the time-locked safe unlocks, allowing them to escape with their briefcase.
The guarding-intruders can pick from three spawn points, including ziplining from a helicopter.
Many small secrets to discover and interactions, such as vehicles and every light being able to be disabled.

Custom game mode: Rush
Respawning is enabled.
Intruders must reach a goal point within 5 minutes to reset the timer and move the spawn points forward.
The map is a recreation of the first three levels of the Goldeneye 64 campaign (Dam, Facility, Runway)

Custom game mode: Wiretap (hack)
There are 8 phones that randomly spawn throughout the building.
Intruders must find and plant bugs in 6 of them to win.
Intruders have a screen in their spawn area that shows any moving object within the building, so they can track the guards at all times!!
But, intruders spawn with no guns, besides a single sniper rifle in their spawn area.

Custom game mode: Bomb Defusal
Respawning is enabled.
At the intruder spawn zone, there are two "bomb arming" codes. One for upstairs (B) and one for downstairs (A). Reach the bomb plant zone and enter the code to place the bomb.
If the guards can defuse the bomb (again, by entering a code) before it explodes, they win. Otherwise the intruders win when it explodes.

Classic game mode: Raid
This is a normal "briefcase" mission, except, it's extremely dark outside in the woods... so there is a custom Night Vision Goggles mod added!
https://psteamcommunity.yuanyoumao.com/sharedfiles/filedetails/?id=1844550541

Classic game mode: Raid
Playable Work in progress!
Fairly large map, but the two briefcases are fairly close together, and most of the museum is contained in two large open rooms. The remainder of the map gives Intruders many choices on how to approach the objectives.
