Since the Mod Messup page died due to unknown causes, this is basically the second link of Mod Messup. JK! It's actually it's own mod, but it's estimated to be released along with Mod Messup. Plus it's demo will also be stuffed along with the Mod Messup Demo so there will be two mods released in one!
This is the LP-25 sniper rifle, it's meant to replace the LP-24. Since the TF:RE "Good guys" now rely on nanotechnology rather than hazardous environment suits. It's still got the LP-24's features such as the G36 like appearance and the "One Shot" bolt action feature. The changes that were made on to this gun were; it's now got the "R" fire mode which stands for "Rail gun". This allows the user to fire random projectiles that's 12.7x99mm or below without damaging the rifle. The "accelerators" aka the rail gun coils are now hidden within the barrel rather than sticking out on the flash hider. And finally the rifle can hook up to the nanotech within the user, making it easier for the user to hit their targets and also repair the gun without having to take it apart. If the user is bored, he or she can access the internet using this rifle with his/her nanotech and they can chat with their friends or play apps with it without disturbing anyone! Other than that it's basically a .50 variant of the LP-24.
