Maybe you could compile a bunch of spikes together to one object, especially the outside the ring, make a single object out of them. Or you could completely remove these spikes (on the outter side) and put some lava/kill zone there?

Because I REALLY LOVE the use of spikes, but the one around the arena dont fully serve their purpose, they're not always killing dudes that land on them and the spikes themselves are easy to miss anyway :P

Thanks komander! I actually already thought about about replacing them with lava, but i'm not sure if that would "destroy" how the map feels, if you know what I mean. A kill zone could be a solution, I have several ideas for that...
And about compiling them to one object: I don't know if this would work or if that's even possible. I grouped them together, but i don't think this makes a difference...

what about a ragdoll zone that dosent go to the bottom completely

why not fully to the bottom?

they cant stand up again and cant get killed, since you'll ragdoll too if you go down there. and if they bug up the spikes, they'll fall repeadiatly(dunno if i spelled that right) and eventually land on te spikes

My idea is to get a better PC.
Works everytime.
