These are the ones I can think of but Im just curious what DB is more related to (most!)
What game is DB most related too? *most*
it reminds me of double action boogaloo. probably with the combination of jumping and gunning
Quake 3 arena for me. I used to play instagib TDM with the railgun all the time and in DB I main Vassili. So it’s very similar
Lol… Is this a trick question? Did you mean besides wolf and quake wars?
Don’t know why it reminds me of it. Oh yeah, I used to play a Warcraft mod with skills and shit for like a year or two, that was real fun.
it supposed to remind you of et and brink, though et was enjoyable for me this not so much
You wished it was like Double Action Boogaloo.
Actually…can we have a double action boogaloo merc who just jumps off things and does physics defying aerial acrobatics while sliding around and not really being very effective at killing anything (mostly cause I took the weapon that gives me 3x points)?
When I saw Rhino, first thing that came in my mind was:
“Did they get inspiration from Heavy, from TF2?”
Nader reminds me of Demoman.
Vasilli reminds me of Sniper.
Phantom reminds me - more or less - about Spy. (I know that Spy doesn’t have SMGs, but that behavior is another story.)
Bushwacker is like Engineer from TF2.
Rhino being like Heavy I mentioned already.
All of them aren’t of course “exact copies”, but they remind me from each others quite a lot.
But that’s not a bad thing of course, I loved TF2 as well. 
The gunplay and speed is 1:1 Enemy territory, just smoother and modernized.
Wolf/ET/QW/Brink/Urban Terror/Action Quake 2/Soldier of Fortune 2
DB has a lot of qualities in common with those games/mods. DB is most likely inspired by earlier SD efforts as opposed to the others I listed but they still share many of the same features and gameplay.
some of you guys are wondering why i didnt add brink yes i know Dirty bomb is like The most related to Brink and lots of ppl know that so i was thinking why not think of a 2nd game that relates to it the most so yeh
