Why so official?
Do you wish to have some feed back on your really good mod "S3 Redesigned" dear Mister WerHeruvin ?
Definitely not a mod bug. It looks like you forgot to put his file s3Redesigned.l to your Silent Storm Sentinels/Scripts folder. Once you put it you will have to reload from the Global Map.
I found that for every former Silent storm random encounter you had, I just can not exit, the weapons service pannels never open, and you have to reload to avoid this random encounter.
Double check if you installed all files corectly.
Are you using some other mods with Redesigned simultaneously?
Are you using GoG, Retail or Steam version of the game?
You can damage undead by melee or throwing, grenades or engineer stuff. Bullets/rockets won't work except if undeads are critically wounded. They are immune to critical effects like blind, stun etc. Death critical will kill them.
And one question : how could my team kill the zombies? I try every weapons Mines, grenades,... nichts! nothing working and each member are level 24.
One more hint: if any undead will be torn apart (like with an RPG grenade), the script will hang meaning all undeads will become vulnerable but you will get stuck on the map — bug.
thanks, and you did a pretty good job.
