If you’re a fan of the Castlevania series from the original NES, then this pays it homage and is just bad@$$. Although I don’t really remember Simon Belmont using a gun ever.

Just when I thought the NES L4D would be the coolest thing I see today, I find this gem of a post by Kreyg. This was a pretty good effort by whomever created it.
that is the coolest thing ever
When he pulled out the gun, I was like: HAAAAXXXXX! lol
this is awesome sauce, wonder if it was…nah won’t work
This is amazing. It’s also a great example of what you can do to a game with a skin. And of what you can do in a different viewpoint. Changes things up in a way. Imagine first person mario. It would be pretty interesting to see, even if it sucked.
dude, http://www.youtube.com/watch?v=TVScsrgKps0 there is one! haha
the sad thing is that I would actually buy this. I love both series
Man, I wish I knew how to do cool stuff like this. These types of HL/HL2 user maps are always amazing.
Oh my Jesus Christ. That is awesome!
