Hey guys! I am Matthias Hilke, Product Manager at ClockStone Studio. Since we released [b]Bridge Constructor Portal[/b] together with Headup in early 2018, more than one and a half years have passed and we have received a lot of awesome feedback from you. We are really happy about that! We love [b]Bridge Constructor Portal[/b] and want you to have the best possible Portal experience with it! So, with the fresh [b]Bridge Constructor Portal[/b] Content DLC "[b]Portal Proficiency[/b]" you are now able to [b]place portals on your own[/b], which adds a whole new dimension to the game! https://www.youtube.com/watch?v=1vvfg_V7ML8 Here are some useful tips and tricks that might help you survive the Portal Proficiency chambers: [b]Test Mode: Deconstruct complex levels[/b] Test Mode – what does it actually do? It activates the physics system but without starting the vehicles so you can check if your constructions are stable by themselves. It also activates all Companion Cube Dispensers and High Energy Pellet Launchers - as long as they don't require additional trigger mechanisms, like pressing a button for example. So, if one of your tasks in a test chamber is to redirect a cube onto a button, you can use Test Mode to focus on that before meddling with the vehicles. Of course, in some cases the path of the vehicles might cross the path of the cube so you might end up doing some adjustments after testing it in Drive Mode. However, Test Mode often helps a lot to deconstruct a complex level and solve it step by step. In the case that a cube dispenser does not spit out a cube in Test Mode, check again if it needs another mechanism to be triggered. You can easily check this by examining if there are cables running to it. No cables mean it should spit out a cube without further ado. [b]Non-linear test chamber access in Chapter 3[/b] Over the course of the DLC, test chambers are getting more difficult and complex and the later ones might take some time to solve (not necessarily though. I don’t want to frighten you unnecessarily. Hey, this is me, Matthias, not GLaDOS...). To avoid that a chamber you are particularly struggling with prevents you from enjoying the rest of the game, we decided that all chambers of chapter 3 are unlocked at once. So, if you get stuck in a chapter 3 chamber, you can quit it for a while and try another one. [b]The Build-all-struttings feature[/b] This feature eases the building hassle a little bit. It allows building several connection elements (the rigid ones, not the cable) in one single step. Press ‘Ctrl’ on your keyboard when placing a new element with your mouse and it will automatically build all connections that are indicated by the dotted preview lines. If you prefer solely using your mouse, pressing the mouse wheel instead of the left mouse button does the same job. But don’t rely on it too much! It will only complete structures for your convenience. You’ll still have to do some thinking and come up with a reliable construction! [b]PS.[/b] Some of the more complex levels might give you a hard time but don't forget: the harder you have to try the more rewarding the feeling will be once you have solved them! ;) https://store.steampowered.com/app/1113550
