So I finished the game and got information that I collected 14 Cheesy Poofs. They were in tough to reach places.

After googling it, it seems that if you collect all 20, you get a different scene ending. It also says that if you find 4 calendars (I found 1 only), you get an extra scene in the ending.


"The expansion has two minors ones: a set of four different calendars can be found. If Blade gets all four of them, an extra cutscene plays during the ending. The second are an item ("Cheesy Poofs") that if enough are found, a background detail in the ending is replaced with a giant spinning bag of Cheesy Poofs."

Anyone knows if it's possible to use cheat codes, or otherwise how to see those endings? There seem to be precious few resources on Youtube about it.

Sorry, can´t help. I never found all of the cheesy poofs. And I never have even seen a calendar. They must be very well hidden.

One of the calendars. Is in the penultimate level (Breeding facilities). In the glass room with the 2 goons, just before the one where you pick the nuclear weapon. You have to "use" it to pick it up.

I must have seen others but had no idea they can be picked.

Anyway, I found a solution. If anyone is interested.
I extracted the map and found the relevant variables. I have no idea how to change them using the cosole though.
game.poofs_pickedup
game.nudiepic

The first one is for the poofs. The second for the calendars.

Since I had no idea how to change them in the console, I just created a new script for the final map where these are already set to the required value.

So if you want to see the ending.

Download the nuke.zip file here.

In your game folder, go to to 2015 folder. In it, create a folder called "maps" if there isn't one already. Extract nuke.scr to it.
Start a game and go to the final boss level. Note that if you try loading a game that was saved in that level before, it will not work now. You have to enter that level again. You can do it from console by typing "map nuke".
Kill the boss and enjoy the extra endings.

Provided as is. Always backup in case anything goes wrong. To undo, remove the file from maps folder.
