P90

P90 (or Project 90) is a compact personal defense weapon (PDW) designed as a Submachine Gun (SMG) chambered with powerful 9x19mm Parabellum shells. This weapon was designed by FN Herstal of Belgium, and saw widespread use. It is a mix of high durability, fast fire-rate, high accuracy and high clip size which made the gun's design pretty weird. Currently, the P90 is located in Armories located at LCZ near guard spawns, or can be archived by putting Glock 22 at 914 on Fine, or Honey Badger at 914 on Coarse

Tactics
P90 is great to control the facility at normal circumstances and it also works great when used as a personal defense and attack weapon against Chaos Insurgency raids. It's damage is acceptable, recoil is pretty low, manageable reload speed and good clip size. Its disadvantage is when fired, it triggers a pretty loud sound. This gun can be the best gun for whose using this carefully. Be careful if you see a champ blasting with P90 effectively, you need to wisely fire back with your firearms.

P90 vs Honey Badger
The Honey Badger seems to be designed for rapid-fire and fast attack purpose (high damage, firerate, manageable clip size and reload time, also HB seems to be some kind of AR-mixing); but the P90 is designed for personal defense, means that in exchange of damage, we have steady firerate which will ensure you to control the muzzle lag, pretty good accuracy (which is in the middle of all) and trustworthy clips in-hand. You can upgrade to Honey Badger if you want, but it's not a good way to go when you want to defense yourself from the enemies in a long, wide hall with several mates reloading. Choose wisely.
