The saw blades are win when it comes to disposing of teh Zombies!
Not only do I like to throw saw blades at them, but also tins of white paint!

Paint those buggers white, I say!

PS. Since I had no internets, I recently replayed Half-Life 2: Episode 2. Yup, cried again at the end!

PPS. Oh yeah, I got that Gnome to the rocket too! (Couldn't manage it the last time I tried) Thing is, I have no idea what it did! I looked up at the sky when the rocket went up, but I couldn't see Gnomey!

(I put him in the little door thing on the rocket, then shut it)
PPPS. I has screenshots to prove this. Will post them soon.
