BAD

What happens?
You save no-one but yourself. You have been very selfish!

How do I get it?
Don't go to the Annie's Bar or the Motel to visit Kaufmann and don't save Cybil at the Amusement Park ( as much as you want to do so)

What do I get for completing it?
You get to access the Chainsaw, Rock Drill and Gas Can in your next game.

GOOD

What happens?
Only Kaufmann survives.(Dont ask why this is Good!)

How do I get it?
Take a detour to Annie's Bar and then the Motel to help Kaufmann out, and don't save Cybil at the Amusement Park. Kaufmann will then show up during your final battle.

What do I get for completing it?
As with the endings above, you get to choose between the Chainsaw and Rock Drill. Additionally, you'll receive the Channelling Stone which can be used to arrive at the UFO ending.

GOOD+

What happens?
Both Kaufmann and Cybil survive.

How do I get it?
Take a detour to Annie's Bar and then the Motel to help Kaufmann out, but also make sure that you save Cybil at the Amusement Park, as detailed above. Both Kaufmann and Cybil will then show up during your final battle.

What do I get for completing it?
As with the endings above, you get to choose between the Chainsaw and Rock Drill. Additionally, you'll receive the Channelling Stone which can be used to get to the UFO ending.

UFO

What happens?
Harry is spirited off by aliens!!

How do I get it?
You have to have received the Good+ ending first. Then use the Channelling Stone at the following locations: 

- On the Roof of the Alternate School, after you've opened the valve;
- At the entrance to Alchemilla Hospital in front of the gates;
- In the Motel Car Park before you visit Room 3;
- In the Boathouse after the meeting with Dahlia and Cybil;
- On the roof of the lighthouse after Alessa has appeared.

What do I get for completing it?
You'll access the amusing secret UFO Ending and you then be presented with the HyperBlaster from the benign Aliens, a firearm with infinite ammo- what more do you want??!!

BAD+

What happens?
This time you save Cybil (Yippee), but you don't meet Kaufmann again after the Hospital.

How do I get it?
Don't go to the Motel to visit Kaufmann, and make sure to use the Empty Bottle to collect some of the unknown liquid from the Director's Office in the Hospital. Then, when you're about to commence your battle with Cybil, throw the contents over her. You'll be able to avoid the fight with her altogether, ensuring she survives (Is this Bad?)

What do I get for completing it?
Again you get to access to the Chainsaw and Rock Drill.
