This is just to get it out of my head, love ya dev, but i get you might not have time to add any of these:

- -> Placed in a vent, this items "cools" it (visibly very blue, getting more dark over time) - a cool vent deals mild damage, starting at 1 dmg/5 sec and ramping up to 5 Dmg/sec after a long while. Can be shot/destroyed.

Grappling hook

Net

Rope

"Choose your sound, sound player"

Glass cutter (slow process, but can make a hole big enough for a player in 20 sec or so)

Lock (locks a door, forcing lockpick again) - can be shot

Door stop - can be removed from both sides, removing from the "wrong" side takes medium duration (20-40 sec) - can be shot.

Metal detector (placeable on wall) - beeps if anyone with any metal moves though - users can drop items and pick up from other side or disable.

"tools, mechanical"

Speeds up all processes using vents and doors and stuff

"tools, digital"

Speeds up all hacking interaction

"Running shoes"

Blood bag (fake a bleed while you hold left mouse, let go and it ends, will drain over time)

"Connector"

-> Any trigger of any device will trigger anything connected to the connector and it connects to all things owned by the same player id.

So a room with a laser sensor + c4 + connector does what we all wish c4 would do with a sensor on it, on its own :).

Camera - will give you a jpg of your chars current pose and weapon as a decoy (paper) placeable or as a spray

Walkie-talkie (placeable) - to lure/distract enemys.
