What is the purpose of this mod?
A content expansion focusing on adding more late game content in a more "Robust/Barebones" theme. Currently there isn't much however I intend to add quite a lot more items. Every item is intended to have some form of animation. Most of the things can exclusively be found in separatist outposts as I feel the vanilla game doesn't really give you a reason to side with them.

Current Content
PCORS-10/80
Man-portable rocket gun made to deal with mudraptors/crawlers/etc. Features fairly inexpensive somewhat weak ammunition along with some fairly expensive higher tech rocket variants.

PCHBA-30
30KG Breaching Axe with two aimable melee attack animations. Can damage ballast flora. 
PCHMG-7
Rapid-fire heavy machinegun, medium damage with heavy lacerations. Uses the extremely high pressure 7.28x48mm cartridge which is necked down from 20mm. 
PCHG-18
More powerful harpoon gun meant to be used with an exosuit. 
PCBD-40
An inexpensive albeit dangerous breaching device, basically a shaped charge on a stick. 
PCGL-26A3
A heavy automatic grenade launcher with three types of ammunition available:
PROX-HE

AP

HEDP
The weapon also includes animated firing and "reloading" along with an overheat system. Use of an exosuit is heavily encouraged as otherwise you will receive a concussion debuff. Repair "broken" status from overheat by recycling in fabricator.

PCRRP Shells
A set of 3 rocket propelled railgun projectiles which includes a normal armor piercing rocket, a shaped charge rocket and a proximity fuse shrapnel rocket.

PCHWGDL-10800
A fairly large gas dynamic laser welder that uses welding/incendium fuel tanks. Has quite a lot of range and works extremely well against husk. Will cut things somewhat inefficiently if you use oxygen/oxygenite tanks instead. 
PCEAV-15K-C
Combat oriented 15000m depth rating exosuit, completely self powered and with the ability to refill oxygen tanks in atmosphere. Comes with an internal light.
The exosuit overheats from use! Submerge it in water to cool it!
