Fantastic map and I was enjoying till I got to the place where you have to go through the wall and into a yard to fight then come back through the portal. But sadly I had already flipped the switch not realising that if you flip it before you go into the yard when you come back game ends because you cant progress. Disappointed to say the least.
A heads up about NOT flipping the switch till after would have saved a lot of heartbreak at not being able to complete it.

Good mappack. Fights are nice nice, may feel un-balanced sometimes, though. But are pretty manage-able. I Found several bugs which's screenshots have been shared to the Author of the mappack. Pretty fun map, could be boring if you play it in one sitting. Overall, recommended.

The previous music from the Sacred Yards level was much more atmospheric than the new one in the folder. This is about the 3rd level

Nevermind, I learned about it, although I'll throw this out so others can see.
Just put the folder in:
C:\Program Files (x86)\Steam\steamapps\common\Serious Sam Revolution

Where exactly is the Music folder to put the music fix? Maybe that changed for ver 1.03?

I've also met a bug where, when I killed the Electric Aludran Reptiloid after the part that holds the Minigun, they died, but there was still electric balls being cast. Also, high scores aren't saving.

It was really interesting experience. Almost everything about level design is so good, weird and entertaining (yeah, those mechanisms and places with wrong physics). But there some are problems with the gameplay: stupid enemies' spawns - in many moments you have to just stand still and shoot spawning one by one monsters - it's boring. Also in my opinion annoying thing is that at each level you have to run back and forth to use these fucking switches, I even got the feeling that the author has some kind of fetish for switches, haha. Speaking of challenging - I really had to contrive to get through all this on serious! All the same goog job, man. 7/10

ok after a full play through more or less. i have to say i love these maps. sand storm (1st Level) was really cool but a tad too short. it led perfectly into the 2nd map which was hidden temple.

the third map was totally broken somthing with the cutscene at the start makes it impossible to play which is a shame as the quality and craftsmanship that went into these maps is amazing.

thank you for posting these maps

so far only played hidden temple or whatever its called. but it was an amazing map, very talented builder i wish i could build maps half as good as this.

Some parts were a little quiet but they were early on and the map really heats up as you get into it.

the asthetics in this are better then the original maps with well thought out rooms, fights and pathways to go.

unlike 90% user made maps this map dident break in a online coop game which for me atleast is a bonus 9k points.

love it wish you could make a map buliding tutorial to help noobs like me out in building maps.

Awesome level, well what i have played of it lol
