Overview

Intruder is a tactical multiplayer FPS with a heavy focus on stealth - it's Guards vs Intruders, as both teams attempt to eliminate the other (or, in the case of the Intruders, complete their objective). Using a variety of weapons and gadgets, along with teamwork and skill, players can fight across a variety of maps made by the developers or players.

Controls

It might look like the control scheme is overwhelming, but don't worry - we'll break down the important keybindings one by one.

Movement and Character Control

WASD/Mouse	Intruder uses a standard FPS control scheme, where WASD moves your character and the mouse moves the camera.
Primary Mouse	Fire your weapon, or activate the primary function of your gadget.
Secondary Mouse	Aim down the sights of your weapon, or activate the secondary function of your gadget.
Q and E	Lean left/right, respectively.
Space	Jump.
Shift	Toggles crouch on/off.
Alt	Toggles prone on/off.
V	Pick up an item, or use something (eg. press a button).
R	Reloads your weapon. (Enemies can't hear you reload.)
K	Play dead - turns you into a ragdoll. You can still speak while ragdolled, but standing back up is noisy and leaves you vulnerable.
Scroll Wheel (Press)	Press and hold the scroll wheel while moving to sprint. Uses energy and makes a lot of noise - be careful!

Communication

C	Push to talk - hold C to speak locally.
F	Pulls out your hand radio - use LMB to speak into it. Anyone on your team can hear you in radio chat.
Tab	Press to open the hand signals menu. You'll snap your fingers, which only you and your teammates can hear.
Enter	Opens the text chat/terminal. Anyone can see chat messages (unless you're dead, in which case only other dead players see you speak).

Misc. Controls

Scroll Wheel (Up/Down)	Opens doors. Allows for incremental opening and closing - you can throw a door open with a quick scroll, or open a crack to throw grenades in.
Number Keys and Equals Key	Selects equipment/weapons. Tilde (~) holsters what you have equipped.
I	Opens the inventory screen, where you can equip anything you pick up.
X	Toggles your current item's mode. Only applies to the SMG and Binocs.
Esc	Opens the menu.

You can also input various console commands into the terminal (eg. /ms 1.0 sets your mouse sensitivity to 1.0).

Gameplay Basics

There are two main gametypes - briefcase mode and computer hacking mode. Both teams can win via elimination in any gamemode, however.

In briefcase mode, the Intruders must grab the briefcase (walk up to it and press V) and take it to the extraction point, marked with a large purple beam. If the carrier is knocked over or killed, the briefcase will be dropped - make sure to pick it up again if that happens!

In computer hacking mode, the Intruders must hack various computer systems. To hack a computer, walk up to it and press V. You'll need to hack 3 out of 4 computer systems to win, and each computer system has multiple computers (labelled A1, A2, etc.).

The Guards don't have to do anything beyond eliminating all Intruders - there is no time limit on a round. (Don't delay the round!) When a player is killed, they can only be heard by other dead players - you can press the mouse buttons to spectate other players, or press F to enter freecam mode.

If a player is alive but knocked over, an enemy can click on them with empty hands to arrest them - this means the player is dead, but able to use local chat. An arrested player can press the jump button 5 times to enter spectator mode.
