The Warhammer 40,000 universe is a vast place where just about anything can happen. More often than not, however, it's something unpleasant. It stands to reason that when two armies meet for battle, the sun isn't always going to be shining down on a nice grassy field. And you can certainly bet the temperature isn't gonna be a pleasant 72 degrees with a perfumed, honeysuckle breeze!

Wars are often fought in the most treacherous of conditions. Talented commanders learn to use these unwelcome factors to their advantage. In 40K, such conditions can range from intense ash storms that impair visibility to unforeseen infestations of native lifeforms that eat troops alive. The Warhammer 40,000 rulebook has several great lists for strange worlds and detrimental environmental conditions. However, I figured that grim universe could use a few more, especially a few harsh, unforgiving ones that'll make you and your opponent cry like little girls.

The following hazardous conditions and rules are meant to make life tough while adding a twist to your games. They are in no way truly balanced, fair, or official. Most are simply minor annoyances that commanders will have to deal with or avoid. On the other end of the spectrum, a few conditions are just plain crippling for certain races. Like I said, nothing is fair. That's life, especially in the 41st millennium. You can't always pick your battles after all. However, if a hazardous condition is rolled up that you and your opponent don't want to deal with, that's fine. Simply roll again. Or better yet, agree on a one and forget about rolling. Whatever method you choose, just have fun playing 40K!

Finally, if weird circumstances arise from these hazardous conditions (it's bound to happen) or something is unclear, don't waste time with an argument. Just have a good old-fashioned D6 roll off! The higher roller gets his way and once the game is over you can set up a house rule so further arguments do not occur. Remember it's just a game – have fun.
