Tekken 6 Scenario Campaign - Tekken Force 4th Special Forces Operation Group Compound (Eddy's stage)
You get a lot of help in this stage, the Tekken Force fights alongside you, although I'm not quite sure who we're fighting against(I'm dumb sometimes). The soldiers with the white uniforms have guns and are annoying as hell but they add more time to the timer so take them out when you see them. It actually doesn't take long for Eddy to appear. The trophy you earn after beating this stage for the first time is "the key to victory"
