Look, Half-Life is a great video game. We all know that. But have you ever kinda thought to yourself, 'I'm having fun here, but the violence is a little pedestrian for my tastes, why can't everyone just explode into a pile of blood?'
Well, do I have the mod for you.
M249 - Mod DB It's called Brutal Half-Life and -- yes -- it's inspired by the Brutal Doom mod that did the rounds a while back. Only difference it: it's Half-Life.
And crap is exploding everywhere. It's a goddamn blood bath.
By all accounts Half-Life has aged pretty spectacularly, so it might be worth a replay you blood-thirsty bastards.
You can find out more about the mod (and download it) here.
