I tried the orignal Notrium Eons ago.....
Then played Werivar Mod.....so endings sorta confused by now, since i played it so many times.... Some of the times, i can get multiple endings simply by getting the items required but not go there, and attempt the other endings.
Endings, here they are:
1) Blast the 2 Big guns, goto iceland and use modded radio to call for help.
2) Blast the 2 Big guns, fix the silly escape pod and go on a long voyage home.
3) Kill the 2 Queens + their omelettes-maker and become the king of the jungle. lol
4) Kill that green irky monster in Eden, and use the planetoid on altar..... replacing tat irky monster after that.
5) Goto the ship, destroy all and command the mining station, become super rich.
6) Psionic ending - special (using psonic)
7) Become the super robot with the ultimate upgrade (not sure if this is MOD).
Gather tons of rubbish and all absolute items, input to scroll and realise u became God?
Record for playing? I tried surviving for as long as i could, and at 200+ days still surviving.
Tips on Werivar Mod, go for normal, no temp for more fun. Then establish a good base - mine was the super hard base - the Bunker. Hunt for tons of food, set ether generators going, mine like mad, create new items like mad, flood the base with protections and battledroids, and ehem, clean out tat junkyard. Then go for broke - whack as many of those battledroids spawns as u can.
