No, mod launcher will not do server installs. Yes, Starvation can run on hosted services, we use KillServers who know how to install the mod correctly. Pam, our server team member, can help with that server config, which depends on number of player slots you require. Client requirements are covered in the opening post, but the game is a heavy user of both RAM and video RAM. 16G and 4G respectively works great, less than that you will need to adjust settings down.
