Gordon Freeman's Epitaph

The question came up: What words would (will?) be written on Gordon Freeman's tombstone?

My first thought was a Buffy-esque "He saved the world (a lot)."

But on reflection, I like this better:

My name is Gordon Freeman
An ordinary man
An HEV suit on my back
A crowbar in my hand.

I did my part for liberty
With good friends brave and true
The free man perseveres through all
And so, my friend, can you.
