[Munch's Master]

Hmmm, It depenes. If it was just the industrials/outlaws vs us, we'd probably wipe each other out, but we'd have the most surviving due to nukeing them. If the muds, steef etc. joined in, a united Oddworld vs Earth, we would die.
Oddworld with Industrials and natives together is invicble, look at it-
The Industrial technology is above what we have- robots with electrifying gadgets on their heads (Greeters), mechanical implants as legs and jetpacks, electrifying clubs, sodsas that give you powers, weird consumer goods that could probbaly be turned into some sort of miliatry use, Soulstorm brew, tear extractors, electric walls, teelporters etc. (Been said before but I'll say it again)
The natives also are dangeroous-they have magical bows and clubs, shamans with weird powers, Bigface, the Weirdos, ressurection shirnes, the ability to herd animals, Abe's possesion powers, munch's control of machinery and not to mention the Shrykull-worth a nuclear bomb.
If the Cartel had the support of the Natives, we'd put up a good fight, but ultimately fall to superior technology and powers. Also we're fogetting-we've only seen 1 continent on Oddworld-Mudos. Who knows what else is on that vast planet.
