Instead of a "No Portals" mode there should be a "Passive Portals" mode. This mode would have portals on the map already, just not allow new portals to be placed by players. Maybe 3 pairs at a time. And every few minutes, or perhaps every new round, they'd shift to new locations. They'd be more like the teleporters in Halo CE. By shooting your Portal Gun at one of these portals, it would close it for a short period of time. This would keep the CCTV campers from being too annoying, and get players used to aiming at portal walls and pushing that button. This way the "casual" players can still get used to using portals without the pressure of having to manually create them, or the frustration of reacting to players who are much better at using them. Then they can use that experience to enter the "With Portals" modes with a bit more confidence. This helps maintain the game's unique identity in all modes. Brainstorming names: "No Portal Gun" - does the job but it's not snappy. "Passive Portals" - my favourite so far. "Static Portals" - would have worked if not for my idea to have them rotate every round or few minutes. Maybe it still works if it's round-based not time-based. "Preset Portals". Could have a more creative name but would need flavor text right next to it that briefly and accurately explains the difference.
