A small loan of 2k mmr, you should read the description..
"This mod was created with "CRAZY Serious Sam Mod". So, if you want to get true experience, your should download this mod (from here (http://psteamcommunity.yuanyoumao.com/sharedfiles/filedetails/?id=110248240)) and play with it."
Huh, Right?

Level too dark at times at the same time while battling with kleers, you get no ammunition before khnum boss to actually kill the boss (I had to enable cheats after several tries), bombers falling from the sky (what?) and all the times where you just get stalked from behind while fighting enough monsters in front which you can barely kill.

Overall, this map doesn't deserve the first playthrough. It should be made balanced for harder difficulties. As it is right now, it's impossible to end it on hard+, while on normal it is too frustrating.

2/10 for the effort of creating a custom map.

So you visit Newgrounds for your music? Nice. Plus, your choice in music is just ♥♥♥♥♥♥♥ awesome.

Level 4 Peace - http://www.newgrounds.com/audio/listen/395406

Level 3 Peace - http://www.newgrounds.com/audio/listen/472628

Also the peace moment in Level 3. I know it' from Silent Hill, but I don't know which song it is.

The peace moment.

Alex Da Bastardtoucher, in what moment? Peace\Fight?

I'm just more curious as to what the song used in the 4th level is.

Alex Da Bastardtoucher, I will try to find the soundtrack but don't promise that i will find all. But i can pack music in one archive and leave a link to download it.

Neo_minigan Ihank your for the quick reply to my questions. I am still working on the completing the maps.

So far, the campaign seems to be a bit off (e.g. re-sizing certain enemies, like the Gnaars and Kleers), but it had redeeming parts to it, for example, the Giant Khnum being a hell of a challenge, plus adding the Kamikazes makes the fight more brutal). However, the last level was kind of a dissapointment, and adding the automated sentries at the end of the level was a bit unnessecary, as players could just rush right through. Overall, it was kind of entertaining, but could have had more potential. Plus, I really need to know the soundtrack (the music used in the campaign), because the music you chose was really fantastic.

I know about dark screen when enemies attacking - i will see what i can do.
Rus and Eng version have a little different: in eng version you will see english subtitles, but voice main hero doesnt change. So it's ok that you hear russians voice.

I have played the first map and the game is great. Did you make the screen go dark when enemies attack? I think Sam's voice is in Russian. This happens even when I select the packege that ends in _EN.
