K had just t zelfde probleem

.
Maar door wa forums af te gaan heb ik een oplossing gevonden waardoor ik painkiller! dan toch heb kunnen uitspelen

.
K heb het wel gecopieerd van een engelstalig forum (bitje teveel werk om da allemaal over te typen

), maar da zal wel geen probleem zijn.
You can do the outside areas in whatever order, but once you're inside the Monastery, it's important that you do the inside area in a particular sequence so that everything triggers properly. I'll provide a little more detail here. (This will be based on Nightmare)
When you checkpoint inside at the front doorway checkpoint, Devil Monks and Evil Monks materialize. Combo shotgun (freeze then shoot) the Devil Monks, and shotgun the Evil Monks strafing all the while. When the courtyard is cleared, turn around and you'll see a doorway on the right blocked by coffins and explosive barrels. Blow those up, head upstairs. There are 2 monks standing on explosive barrels. After you carefully take them out, go up the next set of stairs and get the last 3 monks on the balcony across from pentagram 3. When you're done, go all the way back down to the ground and head across the courtyard.
Go across the stone pathway under the hanging cross and finish the next group of enemies. After that, the Pentagram 3 and 4 walkthrough applies.
After dropping the hanging cross, and going underground for Pentagram 5, the thing to remember it is a closed area. When you get the pentagram and kill everything, COME BACK OUT.
Mouth of Hell walkthrough applies at this point. As you're going down, go down slowly to make sure you don't run past any monsters by accident. I don't think it's a requirement to kill everything, but you never know.
Than you can try this; in the room youre in (the one with coffins and the one big guy), shoot the coffins, kill the witches, and wait for all the birds to die. After they are all dead, THEN kill the only big dude. If youre lucky, the door should open.
Normaal als ge dit allemaal gedaan hebt, moet die deur wel open gaan.
Have fun ermee!
