What is your favorite robot? it can be any robot, but I would prefer D3.

I love the green robots in Mercenary level 7 with what look like lightsabers

There are a few candidates, but I think overall in terms of design, probably the class 2 heavy driller ("horned owl") from Vertigo. I liked the creativity and texture work on that one.

Yeah that one's for me too. And I kinda like (for a certain value of like, they are murderous machines trying to kill virtual me) Logikill, Canary and Compact Lifter from the same set. & of course there's E-Bandit. Ask anyone.
If you're talking about D3 specifically I'd have to go with Tubbs and Tailbot for their design, and Thresher for his AI -- he's really good at leading his shots and dodging on the higher difficulties and I love the challenge of trying to beat him without getting hit. Although I consider vauss and mass driver cheating. On Mercenary there's the Heavy Trooper cuz again he's got a really cool appearance, a lot of weapons and really good AI but he only appears on map 2 for the actual challenge (on map 6 he's only there to show you how powerful your friendly bots are) so I kinda feel like they wasted him.

One thing that Descent 3 still has for me over almost any other game is the complexity, the attention to detail and the challenge of the enemy AI. You really don't see that in modern games.

I agree about the Heavy Troopers. They were always one of the coolest bots. It's really fun on Mercenary level 3 to turn invisible and watch them.

Map 3 had a different special trooper. The heavies were only on 2 and 6.
And I hated the map 3 guys because their railguns are hitscan and absurdly powerful, and most of the time you get no warning of their attack. Plus they're pretty heavily armoured unless you hit their backpack (protip: use fusion ).

Sorry, I was thinking of the ones with mass driver, I know what you are talking about
