hey, if you'd ever find anything like this let me know cause I've been looking for something similar for so long

Hellgate London oringial, and Hellgate London aka Global on steam. Hellgate doesn't have vehchiles though, but it has similar other stuff, big massive worlds to explore and locations, character creation, but it has unlimited character customaztion randomize, randomize color loot drops, to legendary loot, you can mod your guns with loot.

To me it similar to defiance without the vehicles. But defiance is defiance , so nothing will ever come close to it. People said destiny is, but destiny is a great game, but nothing like defiance imo.

I keep hoping defiance will come back, but the company is ♥♥♥♥. And also alot of games has been shut down over the years without the devs even bothering making them offline playable. Which is why i really do avoid spending money on f2p games anymore, i learn my lesson, most if not all of my fav online games were shut down and no way to play offline.

sucks. so becareful on what games you spend money on.

The Star Wars MMO has a decent vibe to it, might help to scratch the itch

This is late as heck, but you might want to try The Division. Not super similar, but it's an MMO with guns, abilities and stuff. No vehicles though.

Star Wars TOO isn't a 3rd person shooter, Destiny has no trading. I saw some reddit thing somewhere that someone got an answer from Gamigo that they're thinking of bringing Defiance back in some form.....I'm skeptical, but I do a search at least twice a month for any news about the reboot.

Undawn

Undawn is kinda cool....I played that for a few hours....took a bit of effort to get my gamepad to play well enough with it. I need to play a little more to get a more solid opinion of it.

Borderlands, The Division

Project LLL has potential....keep an eye out for it in the future.
