Golden Thighs is annoying piece of deatchmatch, because Jungle Queen has TOO MUCH STAMINA! Even if you use grenades she won't die alongside only 1!

Briefing

Strategy

Run behind buildings and when Jungle Queen tries to get in the biggest building to get some more ammo, shoot about three grenades in it, Queen should die then. Repeat strategy until you win. Depends how fast you can repeat it, you can earn even gold, like me :) Remember, even suicide sometimes helps, like going close to her, and shooting lotsa grenades into the ground beneath you and Queen. You both will explode. But this isn't really idea to use too much times, because there isn't endless amount of grenades spawn in area.
