I have just completed a Cloudy Day mod for Infinity(I thought I'd do somthing besides BG or Deathisland for once)The details of what it changes are as follows, It makes the sky cloudy, sun hardly visible, cliffs have rusty looking lines in them :p, ground has a slight metalic texture to it, the flamethrower is a gravity rifle and believe me it messes with gravity, rocket launcher is a plasma pistol that shoots alot of very high powered charged bolts or 10 rockets with flaming contrail(Rwarthog shoots flaming rockets also)warthog shoots pistol bullets, ghost is faster and shoots warthog bullets plus u sit in it like a banshee

, sniper rifle can push you or a vehicle a little, gun turret shoots very powerfull charged plasma bolts, the flags melee can make someone fly, you can jump to top of level and not die, you walk a little faster, plasma grenades have a huge explosive force, and the banshee shoots very fast higly explosive needles as regular fire and a tank shell as secondary fire. ENJOY!
