Here the instructions to join the server.
1. Make sure you have the prerequisites for the coop evening: 7 Bullets v1.21, Deja Vu v2.01 and Project Zephon v120.
2a. If the server is not running Seven Bullets co-op, connect via usual UT by finding "sana's server" in the server browser
OR more comfortably by entering "open sana.servegame.com" into the console.
2b. If you find that the server IS running 7 Bullets, use your Seven Bullets shortcut instead of UT and repeat 2a.
If you have connected to the server, you have succeeded! If not, something is wrong. It's probably your fault.
Repeat: The server address is "sana.servegame.com" !
And I'm, uh, using the newest version. v239 something. I'm not using a modified olweapons package like dedicated co-op servers seem to.
EDIT:
Thanks a lot for the heads-up regarding MoreMonsters, Psychomorph! The spawning is a tad random and the monsters do fight each other a lot, however I think I'll keep the mutator as long as nobody complains. If somebody does, it'll be easy to switch off.
EDIT2:
ZombieHunter was able to connect just fine. Test succeeded! I've shut the server down.
I'll probably tinker my own version of CoopWeapRespawner to also respawn other pickups than weapons and make some spawnable teleporters if I find the time. Apart from that I think we're ready to go!
