Guess that's how they reflect the sun, the same effect can already be achieved in Open with good shine maps.

Target locked! Commence plasma core insertion! Fire!

Welcome to HLP!
Exits are on the end of the aisle to the left and right, don't bother using them. In case you want to hit someone or just in need of weights flamethrowers are under the seat. Unfortunately we're out of fuel so you'll have to blungeon people to death with them.
For whatsoever reason you happen to find yourself crawling through the ducts and venting you have a more than average chance to encounter a Shiven. Pretty easy to spot with the five legs and all. If its Carl he will react well to food donations, if not or you're just out of food you'll at least die quickly.
In case of emergency plama rifles are stored in the lockers at the front, but will only open for Admin, God, or superinteligent shade of blue.
Have a nice day!
