In Firearms, if you jump off the top of a three-story building, you won't be able to instantly move and you'll also have a broken leg. You could have broken your back or arm or other bone. Broken legs impact your ability to move in the game and your top speed is reduced by approximately half. I love sneaking up on guys with broken legs. After you get really good at playing the predefined classes, be adventurous and start defining your own armor levels and weapons arsenal.
Firearms has a credits system that enforces balance amongst the players.
You'll have to figure out the pros and cons of the weapons against your preferred playing style, and then understand that if you are fond of a particularly expensive weapon, you may have to degrade your body armor or make some other compromise with regards to your kit. The Firearms team could best be served by taking a lesson from the Counter-Strike team with regards to buying weapons. My favorite mission is where one side has to airdrop from C-130s to an LZ and defend a power station. Also, it's always fun to try and kill a parachutist. Summary This is a Mod with a lot of promise.
