Like it says on the tin. Make 'em rare, make 'em space loot. Things like this; Damage I - III Manoeuvrability I - III (I being helpful, III being like an extra bars worth) Energy Efficiency I - III (Slows the energy decay rate by fractions) *** Shield (Damage reductions, perhaps a few elemental-specific ones) Thorns equivalent ('cause those melee space sods annoy the snot out of me) Weapon Speed I - III (Increase ROF from like 5 - 20%) Salvage Unit (Increases salvaged items dropped by enemies) Energy Reserves I - III (Just increase total energy) Road-Runner (Massively increases walking speed) Digger (Increases power of mining tools used by mech) Etc. Throw in ideas, perhaps.
sounds good to me, especially salvage unit or digger. i remember reading in another thread that high-end mech mining tools are still slower than a fully upgraded MM. might as well make some way for them to be relevant
