The final boss scene from Portal 2.
I'm pretty proud of this, although I forgot to add a few things.
Things I forgot:
The space core
The Repulsion Gel
Wheatley's bomb-proof shields
Oh well.
About this creation
Chell using the Conversion Gel while Wheatley tries to discourage her.
The corrupted core named Rick self described as an "adventure sphere."
The broken catwalk and the portal surface used to get on it.
My Wheatley has a hidden projectile launcher to simulate the bombs he throws at you.
