More tools/specials based around portals. right now the porta portal is the only one that really interacts with portals, it would be nice if more tools did that so here are some ideas:

-Portal Wall disabler: creates a glitch in the surrounding portal walls for a tempory amount of time to prevent your team from being flanked

-Portal Vision: Allows the player to see through other peoples portals

-Portal Jacker: Scrambles enemy player portals so they are teleported to another random portal rather than their own

-Portal Trap: creates an energy field over an enemy portal that stuns the enemy's guns when they walk through the portal

Porta h***: creates a large porta portal on the floor that teleports anyone who falls into it into the sky

Poral Shield: A Riot shield that has two small portals on it that can be used to block and return fire if it hits the portals

it'd be nice to have more portal based items and abilities.
