📋 About This Mod
Made by DaiShi Description: This mod places a MEC Gauss Minigun (from Fallout Tactics) in Citadel Lyon\'s Den and Fort Constantine (next to the door in the same room as T-51b). Uses 2mm EC as Gauss weaps should be. Since i made the ammo (and i dont want to mess with loot lists) i made respawning containers w 1000 rounds inside, and modified the The Outcast Collection Agent quest so u can ask for 2mm EC rounds too as reward. (Yes i Know this means some ppl ll have problems w ammo, but hell this weap had ammo problems in Tactics too) Weap stats are from minigun but heavily modified: - base dmg: 7 (0/87 DPS) - fire rate: 25 - ammo cap.: 250 - on crit: knockdown - exploding limbs - weight: 25 Can be repaired w miniguns. (please note i dont have Operation: Anchorage so i cant use the Gauss Rifles projectiles or any other thing it includes) ---------------------------------------------------------------------------- Update 2: Made CALIBR compatible .esp, changes ammo for weapon, in the respawning boxes and in the outcast quest. ---------------------------------------------------------------------------- Update 1: - Made custom textures for backpack. (thx to LORDSKIPPY123 for letting me know the texture bug w orig minigun backpack textures) ---------------------------------------------------------------------------- Known Issues: - the ammo lock is not in its place in 3rd person wiev looks like its placed where the miniguns lock should be, dunno if theres anything i can do about it - If u use a mod that changes Protector Casdins dialog it ll most likely conflict with this mod, but just with the Outcast quest part, so weapon remains usable. ---------------------------------------------------------------------------- Installation: Unzip it in Data folder it comes w 2 .esps: MEC Gauss Minigun.esp - as above MEC Gauss Minigun (CALIBR).esp - as above (uses CALIBR specificed 2mm EC) MEC Gauss Minigun (Megaton).esp - only 1 weapon and container near PC\'s Megaton house NOTE: - USE ONLY 1 esp there are some overlaps in them which can cause problems - i\'ve included pipboy image w description copy it in Data folder (let it overwrite) if u need them. - by request i\'ve included meshes and .esps with minigun backpacks copy it in Data folder (let it overwrite) if u need them. - i\'ve included the minigun projectiles cus the projectiles distorsion can cause heavy slowdown, copy it in Data folder (let it overwrite) if u need them, or dont like the sonic boom of the original projectile. ---------------------------------------------------------------------------- Future Plans: - if i have the time ill work on the texture but i think its the best i can make with my limited knowledge ATM. ---------------------------------------------------------------------------- Have Fun! And use the mod as u like (give me Credit plz if u modify it) Oh! and it\'s the 4nd time I ever done something like this
