Script, the battle on the shovel.

[IndeecFOX]

Dear experts, I'm a gamer from Russia, and I have the AOS server, I need a script that would have included every 5 rounds round, where they can be killed only with spades.

So you want somebody to code a script which makes you after you died 5 times for one life only spades killable? Sounds cool on the one hand, but on the other it would be really annoying because the guys which were only spade-killable were able to shoot the others...

I think that he is asking for a script that on every fifth game round will make the server spades-only.
meleerotation.py in https://github.com/matpow2/pyspades-userscripts will do what you want, just add it to feature_server/scripts and set ROTATE_EVERY to however many rounds you want between melee rounds. (I'm assuming that by rounds you mean intel captures, here)
