I found most of these emblems on Google and edited them slightly for the look I was going for. I made the Zelda and Gears of War emblems as I couldn't find any I was happy with...
The emblems are from - Halo: Reach, Star Wars, Borderlands, Gears of War, Zelda, Metroid series and Mortal Kombat.
Credit to ~TriforceJ
for his Samus symbol ^^
I don't take credit for any of the symbols I didn't make and give complete credit to the people who made the other emblems.
