Here is the list of levels for HQ2.  They are open to anyone to make.  I don't plan on starting on any of them until after ruiner is finished.

A couple notes before we start the list:

Secrets always contain one of the following:
Weapons, this is the only way the player finds them!
Armor pick ups
Large med kits
Large ammo pick ups.
short cuts
or secrect exits.

This will help make it very rewarding to find secrects.  Being able to only find the weapons this way will boost that further.

You'll notice that each little bit of level info also contains what weapons are found.  Weapons are listed twice because this gives the player a second chance to find them.
Their second chance to find them could result from killing an enemy that carries it, or yet another secret.  Always remember never to put an enemy in a map which could drop a weapon before the player has a chance to find it first.
The only weapon that breaks these rules is the machine Gun because once it is gained, the pace of the game is set.

Bosses:
Always remember to introduce your boss.  The music needs to change, and there needs to be some sort of intro.
Because setting up cinematics can become a chore, we'll use a simple rule to help make it easier...
[b] Only Bosses or mini bosses will spawn in via teleporting. [/b] 
This will give the player a clear signal it is boss time.  The demon spawning, the size of the enemy, and the music changes will really help introduce them.
A good example of a game which always gives you a clear indication of a boss fight is Mega Man.


Another note on Bosses.  Some of these guys like the revenant are suitable for more than boss fights.  If you wish to use them in a level, just make sure it is after their boss level.
