Teleportation Gun Game with HUD: aaqh2q


Teleportation Gun Game without HUD: aaqv45

Battlefield Portal is a lot of fun and the community there is very friendly.
The editor is not that hard to understand when you either know programming or have some time to figure it out.
Creating Game Modes can be tedious but seeing random players on the internet having fun in your modes is a great thing. That is the reason why I urge you to do the following:

If you are a Portal Creator or know the Experience Code of a nice game Mode, please feel free to post the code with a short description in the comments to spread new and interesting game modes to a bigger audience.

Lastly if you find some Bug (that lies in the Game Mode itself) pls let me know, so I can try to fix it.

Have a good Day!
