This one is very similiar to the first one.  :)  This continues the logic a little longer.  :)

Wow, nice finish...I think I did the first one earlier...

What a mess!!

How in the world did they come to that position in the first place? I like puzzles where the setup is feasible.

lol it's cool =D but random.

I believe there is a simpler solution though...:

1. Qg8+ Rxg8

2. Ra3+ Bd4

3. Bxd4+ Rg7

4. Bxg7 #

But I do like the ladder theme.

RobKing, you appear to have missed that 1... Rxg8 is check! This actually means white will lose after 2. Kh2 Qh1#.

Robking, you do have a good eye there.  :)  But with the white king on g2 then Rxg8+ is putting our king in check as Nytik mentioned.

ahh good point, I didnt note where the White king was. Sorry about that. I just looked quickly at the problem at work. Very nice problem indeed then!

I just noticed something.  :)  I think this position is an illegal position.  White cannot get that pawn structure with only 4 captures.  White needs 5 captures, but only 4 black pieces are gone.  It had a nice theme to it though.
