OnosBlocker

• First version of OnosBlocker.
• The cvar prs_onos_minplayers determines how many players must be present (excluding ready room and spectators) to allow Onos gestation.
• If the number of players drops below this number, players who have already gestated to Onos are unaffected.
• The cvar prs_onos_minhives setermines how many hives must be built to allow Onos gestation.
  
• If players attempt to gestate to Onos while the number of players is below prs_onos_minplayers, they will recieve a message like this: "You need 8 players to go Onos (currently 7)"
• If players attempt to gestate to Onos while the number of built hives is below prs_onos_minhives, they will recieve a message like this: "You need 3 hives to go Onos (currently 1)"
• Players can use the cvar prs_onosblocker_version to filter servers using this plugin.
