📋 About This Mod
Replaces the MW5 Mechlab with an MWO-like, fully unlocked Mechlab. This allows mechs to use any equipment (eg ECM, Probes, Jumpjets), as well as swapping internal components (eg engines) as well as removing "sizing" from weapon hardpoints. Everything uses the critical slots for size, much like tabletop Battletech.
Compatible with MW5 version 1. 14. 390 / DLC8 Patch 2
Co-op compatible. Controller and Steam Deck compatible.
Mostly compatible with importing vanilla save games, including vanilla mech mods.
Load order: don't touch it. Seriously. Unless specifically stated otherwise, leave it as it is. Even then, you still likely don't need to touch it. If in doubt, ask on the discord. A lot of the "conflicts" are intentional.

Expanded salvage system:
If a destroyed mech does not roll up to be salvaged at the mission end screen, they can drop partial mech salvage pieces.
v1 system: Generic pieces per mech chassis (not variant specific). To assemble a random mech (non-hero, non-unique, intro date allowing) from this salvage, you need 1 piece per 5 tons of the mechs max tonnage (eg a Locust needs 4 pieces, and an Atlas 20). Mechs added by mods require the creators to create salvage items to support this system. Uses inventory items (can be sold via the "all misc" tab in the market) and as such contribute towards game engine inventory limi
