I've tried putting the "+enableretaillevels" command in the command line from the 'Advanced tab' with Nightmares and extra crispy enabled. Then I chose 'Custom level' in 'Singleplayer' but it said 'No custom levels are available' .

I'm not sure if I've done this process correctly to select every level in the game. Am I missing a step or do I need to try a different command?

Extra Crispy is a great mod for Blood 2 by the way and I still prefer it over the vanilla game.

Thank you.

it's +enableretaillevels 1 with no quotes (what quotes?). Is there a a space between the one? Let's seeee...

EDIT
Why yes, yes there is a space. The map in question was 21_LABORATORY

I inputted the command as you described and it worked. All of the levels were accessible from 'Custom level'.

Additionally, I went into level 21_laboratory (research and development) through the custom level list using the modified exrtra crispy file you made.

I am happy to report that your file worked! all of the keycards in this level were both visible and collectible. I even tried this level through the same process with the original version of the file 'EC-EnhancerPack_v1.0.REZ and sure enough - no keycards!

I even tried this method without the extra crispy mod and the keycards were both visible and collectible.

You were right about the extra crispy mod being the cause of the problem and now I am so happy that I've been able to finish Blood 2 without anymore problems.

I would strongly urge you to make other players aware of this problem and how your changes to this mod can fix this problem.

Thank you both very much for your help and support on this problem. I am happy to report that as far as I'm concerned, this problem is now solved.

Thamk you again.

Your welcome jr35659. I'm glad somebody replicated my results. The fact that it was you was even better.
First off we need to clarify that it is the Lie flat weapons mod that Enhancer pack incorporates that is the cause of the problem. I've felt that LFweapons should be in every B2 mod for years so this is an unpleasant surprise for me. EC with the POWERUPS folder deleted works fine. I've been testing level 21_LABORATORY on and off and have discovered some strange instances that involve other powerups as well. There's a 3rd key card next to a bath that can be picked up but I can't see. The singularity gun in the last room where the level ends is missing. Most interesting of all is why these things only mess up on level 21?

As for the Enhancer Pack, it belongs to Johnnycrystal. He can do things in source while I'm stuck with winrez / modeledit changes. I'm sure he will make alterations that are better than anything I can do.

Of Couse. Please give my regards to Johnnycrystal for his fantastic mod. This game feels more like the original Blood 1 with his extra crispy mod and has better, more modern graphics as well.

Well, I'm off to pile up some bodies in the Nightmare levels now that I've finished the original Blood 2.

Thank you both once again.

Thank you for those nice comments but Tren needs props more then anybody. I plan on releasing a patch in the near future that will bring back the Dual Mac 10's and give them a new animation for when secondary fire is used with both of them. That way the player can wield two of them and have a secondary fire option. When I do this I will remove the Lie Flat Powerups which will fix that bug you found. I think I'll keep the Lie Flat Weapons because I've never had an issue with them and I've never heard of anybody having an issue with them. Let me know if you have.
