Churches are large buildings, containing several rows of the seats before a small podium. Churches can only be found in the cities of Kin, Vernal, and Mason. They are usually the epicenter of civilian-grade loot, such as the Maverick 88 Shotgun. Due to their unbreakable windows and single, small entrance, they are a great fort for any team of any size because there is only one entrance. However, due to the high chance of item spawns, they are much more popularly used as personal item farm.
However, making a fort at Churches may backfire against you due to that a siege can render the occupants in a sticky postition, unless they quit (which is a noobish move). Due to the single entrance, a smart player may plant plenty of C4s or mines near it, then camp behind one of the barricades. The occupants inside can only really die of boredom of getting stuck and have nothing to do or get shot when they try and go out. If you plan to build a fort at the Church, remember to build a sniper tower/hideout to ensure no one is outside, wating to amubush you.
