1. Cool gun skin!
2. How do I use the guns. I'm not sure how :c
This is a blade skinned as a gun. If you would like to use a real gun skin, go to a different thread.
Guns are mostly used for PvP purposes in maps such as Cave Fight. I personally (I don't know why) use them for support for titans and punks (very useful, as you can shoot their legs from up to 20m away). They are very glitchy, as they were made for PvP originally, and not very developed for fighting titans (for instance, shooting the nape almost always has the result of going through, possibly hitting the eyes instead)
but that is if you don't o enough damage, 80 for the puny guys, 100 for the next biggest, 200~for the next biggest guys, and then 300~ for the biggest guys, and this is without custom titan size, people who make the titans uber huge when they know it takes damage to kill titans with AHSS are just -sigh-
