heh had to embarrass the guy. :looks around for incoming banhammer:
If i remember correctly, the spike grenade shown is exact scale translating form the game to real life. Keep in mind everything in halo is bigger, MC is above 7 feet tall, brutes being even bigger, and when taking in game models and building them on a 1:1 scale in real life, they're huge. I saw another old topic today in the archives showing that a 1:1 scale S2AM sniper rifle is a little over 5 feet long.
