this mod is amazing but it has bugs that haven't been fixed
1. you can't throw grenades though a portal
2. rockets from rocket launcher are stuck in the portal forever
3. helicopter bombs explode when they come in contact with an portal
4. after a long time of use of the portal gun viewmodel weapons and map models become invinsible
5. ammo and anything related to healing (health kit/Vial,suit battery) are not going through the portal
6. portals are not enough big when players try to go to a very high place
