Ok the first one you need to put a tin cup thing up and use the back side as a wall, then put down a red light effect and a blue one on each side, and then i think there was a fuel rod cannon shot on the right side. The second one was a picture takin on a modded map with a million grids everywhere. The third one is in the crypt with a blue light on the right and a red on the left, and they shot a fully charged plasma pistol shot at the mongoose. 4th one I'm pretty sure was something like a rocket and a laser shot next to the guy, and a blue and red light off to the left side of the pic to make the purple. and the last one was just something like a red and blue light and a spike grenade exploding. well those are my guesses.
the second shot on there i actually made check the author pure phoenix and send me a message or friend request for help
if you want the graph one type on youtube "halo 3 modded sandbox" and there's a vid with a link on it its called "graphplanet"
Thanks, man, I tried it before, but it didn't work for me until I searched those exact words. and i found the vid.
This is just a bit of a guess, but the last one looks like spiker shots/spike grenade combined with a plasma 'nade explosion and Juicy FX.
http://www.forgehub.com/forum/screenshot-guides/73515-grafiti-effect.html that is how you do the first effect and a plasma picture shot..... i think.....
From Top To Bottom 1st ScreenShot is A Tin Cup Or Whatever its called with a red light and a blue light beside it and juicy fx on 2nd is a mod the map is called " Everywhere " and im guessing he put a juicy fx on and took a screenshot 3rd is a simple mongoose with juicy fx on getting shot by a plasma pistol 4th is him standing next to a blue light and getting shot in some way most likely a spartan lazer (produces most blood) 5th is him with a sword (makes the glow) and there is probally a wall right next to him and somebody threw a spike grenade on it and it exploded. There you go.
that second picture is one i took did you like it i just took it on a modded map called graph i could give it to you if you want.
