i think something like portal playground would be fun, just to fuck around in
unless i'm wrong (and i'm NEVER wrong!) you can already do that with GMod. atleast i know i've seen videos with gmod's shooting portals
Muliplayer Portal makes about as much sense to me as making a multiplayer version of Tetris.
I disagree. I don't see any way to make it fun, but I'd dearly like to see someone else who can make it fun do it right. It may not be doable, but I think it'd be cool.
What if I would make a map for HL2 Team Deathmatch or Garrysmod or whatever, and then I would make it like how I would make a map for Portal Multiplayer.
Portal CTF idea:
Two teams orange and blue,two bases,flags separated by fizlers(so you cant put portal next to the flag and just do everything easy way),and some powerup on the center of the map(you are faster,bonus turret for your team for some time,destroy enemy portals and prevent enemies from putting them for some time, etc.)
The goal is to deliver enemy flag to your base in time limit,if you dont capture the flag,and timer runs out,flag is returned.Each team also has one turret,and when it is destroyed,turret delivery system(such as for the cubes)delivers new one.
Someone mentioned that you wont know what portal is yours and what is not.Well it doesn`t matter because you can cooperate with your teammates or use enemy to trick them.
But there should be name of the player that placed portal and some sort of indicator to show where is the other portal.
