Duration: Portals typically remain active for only a limited duration before automatically closing. The duration can be adjusted based on the specific design.

Restrictions: Some portal guns may have usage restrictions, such as a limited number of uses or cooldown periods, to prevent overuse.

Target locked: Some portal guns may feature target-lock functionality, allowing users to lock the portal directly onto a specific target location.

Game Mechanics: In games, the portal gun is often a fun gameplay mechanic that can be used to solve puzzles, enable strategic movement in combat, or provide a quick way to traverse the map.
