Before commenting i have one thing to say: This is my first time modding a game a so please be gentle.

I have made a screenshots for you:

I know it is very big and doesn't look that good but as i said earlier thats my first time modding.
Heres another one how it looks like when its destroyed:

I made it very strong so i don't recommend using it before you beat the game.
It replaces the engi cruiser type A.
You can install it with Grognak's Mod Manager.
All of this is made with the FTL mod tool Superluminal and installed with Grognak's Mod Manager.
