The document describes 4 different game mechanics: 1. Tow Hook - Allows players to grab items or objects from a distance using a grappling hook. 2. Lock Overload - A reaction-based minigame where players click flashing squares to unlock doors. 3. Vent Interaction - Players can place alarms or poison gas in vents to harm enemies in connected areas. 4. Hover Trance - While unseen, players can levitate enemies to clear a path. Each mechanic is explained through examples of typical use.

3.  The player will press Mouse Button 2 and a hook will shoot
out horizontally, towards the way the player is facing.
 If the hook hits a collectable, the item will be picked up and
added to the player’s inventory.
 If the hook hits an object with physics, the hook will drag that
object X amount, back toward the player’s location. The player
will be able to click the Mouse Button 2 again during the pull
to release the object
 If the hook isn’t successful then it will return back to the
player and the ability will be able to be used again.
 This mechanic is unique because it pulls objects or collectables
to the player instead of actually hooking the player to the
object. The ability is ranged and can be used when things are
out of reach or just for the player’s convenience.
Summary of the Mechanic

4. Tow Hook: Used on item
• Player recognizes an item that cannot be reached
• Player uses hook ability; hook shoots out and grabs item
• Hook stays attached to item, bringing it back to the player
• Player gains 1 of the item

5. Tow Hook: Used on object
• Player notices that it is impossible to jump to the next level
• Player sees box object and uses hook
• Hook grabs item and player drops it at a convenient
location
• Player uses object’s new positioning to reach the next level

6. Lock Overload
 Player reactively clicks on an
interface where squares are
randomly lit up to unlock objects.

8.  After the lock interface appears, the player will click
on the square is glowing. The glowing square will
change at a fixed pace but to random squares on the
interface and the player will be timed. If the player
clicks the wrong square, the timer will lose X
amount of seconds and will have to restart if the
timer reaches zero. If the players are successful, they
can progress to getting what was locked, whether
that be through a door, chest, etc.
 This mechanic is unique because it is completely
based on the player’s reaction time. There aren’t any
puzzle pieces to put together or other sequences to
solve. The order is always random and unique to
every lock.
Summary of the Mechanic

9. Lock Overload
• Player is faced with locked door

• Player has 10 seconds to complete the override
• Player is successful and door opens to the next level

Mechanic Info

12.  When a player is next to a vent, they have two options;
place alarm or place gas. The sound or gas will travel to
vents within X amount of radius and effect enemies
near those vents. The players can then decide how they
want to deal with the challenges ahead. This ability is
restricted based on how many alarms or gas items the
player possesses.
 This mechanic is unique because it provides a indirect
way to deal with enemies that are too difficult to kill
and it has a high emphasis on level design. Players
won’t be able to use this ability freely so level designers
have the control of game balance. This mechanic can be
adapted to have any function as long as the action is
performed through vents.
Summary of the Mechanic

13. Vent Interaction: Used with poison gas
• Player sees a tough enemy ahead and notices a connecting vent system
• Player uses poison bomb and drops it on the vent
• Poison gas travels through the vent and covers the enemy’s area
• Enemy dies and ends up falling over to allow the player to jump the the
next level

14. Hover Trance
 While undetected, players lift
enemies on the screen into the air.

15.  Platform: Computer
 Number of Players: Single Player
 Controls: Keyboard and Mouse: C Key
 Perspective: Side Scrolling
Mechanic Info

16.  Any time that the player is undetected, the player
can press C to lift all enemies on the screen into the
air and put them in a trance. This ability will have a
large cool down and the enemies will be alerted
once the trance is over.
 This mechanic is unique because it gives players a
way to traverse through the level without any
pressure. This is a high risk/reward situation where
players must time properly to succeed.
Summary of the Mechanic

• Player sees an enemy that would take too many resources to defeat
• Player uses hover trance ability
• Enemies are lifted to the air and a path is cleared for the player

20.  The player attacks by pressing E, shooting out
gamma particles and dealing damage in a radius
around the player’s center. This will do X damage
to surrounding enemies but fill up the player’s
gamma meter with every use. If the gamma meter
reaches 100%, the player dies.
 This mechanic is unique because it is an attack
that the player’s have to time. The attack is very
effective but it will end up killing the player if
spammed over a small amount of time.
Summary of the Mechanic
