MONOCULUS! I noticed many of you are using monoculus as a boss on halloween maps this year. If you do, you also might have noticed the issue where it does not get stunned by players exiting the "purgatory" area, where you end up after you go to the teleport in generates when it switches places. It works on viaduct_event, so why not in ours. I figured i'd ask this and Eric from Valve was kind enough to look into the matter. There is a fix for this now available. Infact it's been available since monoculus was introduced but apparently none of us figured how to do this. I will update Hellstone with the fix too. I thought i would share this with everyone, so you can also use monoculus properly in your maps. The fix! Entity info_target, name it as spawn_purgatory (this is the monoculus teleport exit that it creates when it switches places) - the place where this leads to, this playable area needs to be sealed with trigger brush and make it as entity trigger_add_tf_player_condition. Set the Condition as TF_COND_PURGATORY with Duration -1. This ensures that the "stun" effect is being applied properly. After you exit back to normal world and hit the monoculus within certain time, monoculus will get stunned. Valve handless the effect timeout within the engine, so don't worry about it lasting forever. OTHER BOSSES, HHH & MERASMUS ISSUES Such as HHH stunning players who wear it's head, has apparently been fixed over the last year. Players who wear it's head no longer get stunned by HHH scare! About Merasmus and the bombhead not exploding when you ran at it with it at your head, Valve is looking into the matter aswell as merasmus not healing itself during hiding. He will go into hiding if you have func_nav_preferred set within the map and it's big enough. If i hear something new, i will update this post with new info. Thanks and have fun with them bosses! EDIT: I received a message from Valve and they have fixed the merasmus bomb head not working in any other map than lakeside_event. They will ship the fix within one of the next updates to the game. FIX HAS BEEN RELEASED! Also it is worth mentioning that if merasmus does not go into hiding, it cannot find a place to hide. This means either that your func_nav_preferred is too small or there are players standing in the spots where he would hide on. Also, he does not heal himself when hiding untill he hits level 2. So all in all, i think the halloween boss issues will go away before halloween hits!
