Hey guys,
First of all sorry for the noob question. So... is it necessary for the players to have the mod loaded with their game when joining a server which runs mission powered by @Alive ?
If its possible, what options would be available for them and what not, or if there is more info on that somewhere, please direct me to a website.
Thank you!

yes. ALiVE is required for all sides. It bringes some new objects and so on.

Thanks
