Another recovered space craft from some unknown universe has been found in the water of Europa. While this one seems to be from some very militant race, and very combat effective, its power systems are lacking. It also lacks any defensive capabilities..

I wanted to make a simpler attack sub that also gives my security friends more action. I usually end up as either a captain or engie, so its got a few options for captain, and the engies will always be busy.

The power system is very weak, but I put strong emphasis on its combat capability for fighting pirates, and doing wrecks/thalmuses. As such, it is not very good against swarms. I think I did alright making a balanced sub for Tier 2 . Its cozy enough and is meant for 4-8 players. Although if you wanted more i'm sure it can handle up to 10. You could get away with 3 players and some bots, but might be a bit rough. There is also a tier 3 version included, i would suggest 5-10 players to make use of the dual drop pods.

Armaments: -Depth charge launcher with 2 tubes. (one active one for storage) -Chain-gun -Coil-gun -Heavy hard point -Rail-gun -A second depth charge launcher in the moon pool for drop pods

Features: -Prioritized weapon system. Has its own battery backup, and quick charge super-capacitors that you can over vault for max speed! -Mini Moon pool -Boarding pods in the depth charge launchers for those wild and dangerous Security officers -Emergency repair system. It can be recharged with new fix-foam grenades. (The yellow glassed in detonators)

T3 Additions: -Double Coil gun on the bottom -Turret hard point on the top middle above the brig -Discharge coil on the aft -More Emergency Repair detonators for better coverage -Medical Turret -Even more drop pods -Slightly improved armor and reactor output ( 50-100 extra hull hp, mostly on the bottom and front. 500kw reactor increase) -More ammo and depth charge storage

Known bugs:

Planned Features: - With the integrated camera assembly, I will be replacing the old style to save performance - A true power to weapons feature that diverts all power to the weapons system

Mod Compatibility: - The reactor is in its own room so hazardous reactors should work fine - There is a dedicated surgery room for your preferred medical mod

If you enjoy the sub, please Rate up and/or favorite. I would really appreciate it!

I have more FTL style sub on my workshop if you want to have a look!

Working on updates to all the FTL subs, and then the Zoltan Crusier.
