To play through and progress on Vex 3, you must reach the end of each act. That means avoiding the deadly traps and devices scattered around each level. When you fall victim to one of these fatal contraptions, you'll be sent back to the nearest checkpoint. From there, you have to figure out how to overcome the obstacle causing you difficulty. Vex 3 Acts There are 10 regular acts to work through. As you'd imagine, it gets trickier. The labyrinth becomes more complex and traps more challenging. If you're a determined gamer, there are 9 challenge acts too. These will earn you a well-deserved "Hardcore" trophy. Trophies If making it out of the level alive isn't enough, there are more achievements to make you feel accomplished. You can earn cool trophies for completing an act perfectly without dying, or dying too much. Then there's the Hardcore achievements. These achievements include hidden stars dotted around each level, as well as the additional 9 challenge acts.
