1. This one could be better than the one shot kill, wouldn't be abused so much, but they only need to be hidden from the map, no special attachments.
2. Yes, especially for STPU as they don't have many advantages.
3. That would be for a role play server, doesn't work in a team deathmatch server.
4. I hate drive-by with cars, a minigun could be attached to a car, but I think would be abused.
5. Why not, the name and other tags could be removed while in that event to make it more realistic.
6. No, could get bugged with the ship and it's already pretty hard to go to the checkpoint.
7. Yes, maybe a 5 minute limit, only that it could make lag.
