Blood Winter is a mod of b30 that makes it look like it has just snowed. There are also many weapon changes, which I will explain with the pics.
The assault rifle does more damage, shoots much slower, new model: Battle Rifle

The pistol shoots much faster and does less damage, new model: UZI
There is a working shooting lifepod in place of the warthog, with skin and correct name


Entire island has been skinned

Trees have fewer leaves

New cool blood stains

Overshields is weapon/ammo areas

Numerous other weapon changes have been made, see Read Me for details.
I originally didnt want to post on here cause I thought I would get flamed, but I got good reviews at MGM so I decided to try it here.
Note: I suck at modeling, so the models are L33t's, and they are allowed to be used. Sorry for large file size, ppf didnt work for the b30 map.
