To me the best Idea to start this mod is having to make Skynet/Genisys/Titan (like making a wither), basicly a boss that takes you to the future!
(Terminator/Resistance Dimension) a place where you could explore, collect cool weapons, hack a killed terminator to make a Temporary Robot companion, Gain trust with the resistance, or/and finaly go back home by making a time machine by killing future Skynet. To find Skynet there are several identical camps but only one of them has an underground fortress.
Finally you must destroy the First Skynet your made or els you'd be sent back to the dark future! (If defeating him you could get a robotic crafting unit)
Cool Features from having the Robotic Crafting Unit (R.C.U)
*Can craft plasma rifles and other future weapons(they can either be craft with R.C.U or collected by mobs)
*Can craft laser fences and other decorative stuff to secure your home/base or make traps.
*Can make HK-Tank and be able to Ride on it
*Make a Terminator army of your own!(but the resistance wont like it...)
*Create a terminator with customizable skin from any known player.
*Make a Terminator Disc to play some sick tunes!
*Make the Time Machine(Portal) to go back in the dark future for fun.
I got alot more ideas n' stuff.
I love Terminator, grew up with it, known the concept, and hoping to play a mod like this.
