It would be a pretty cool event that one of the coders to add, It would be a float scramble, It's like Health Scramble but the difference between it that it's Floating and not Health of the Props. Examples: Lockers are in Float: Very Bad when not in events, It would be for example in: Good. Garry's Sign are in bad float It would be very bad* Well, That pretty much explains it.
This has been suggested numerous times, even recently I believe and once before by me as well. It's also been shot down every time. You might want to look into this stuff first.
Uhuh, I didn't knew that, Even though I zapped into some threads in suggestions, Well this looks like a good event. what could possibly go wrong
Keep note that event ideas hasn't been around forever and many people posted in things like "Garry's Mod: Flood" or "Feedback & Support"
