Before you start
- A paid purchase through an official store. This is a commercial game, not a free mod.
- Per the publisher page: Windows 7/8/10, OS X 10.9+ or Ubuntu 12.04+, 2 GHz processor, 2 GB RAM and 200 MB storage; console and mobile editions also exist.
- No ownership of Portal or Bridge Constructor is required; it is a standalone title.
Find the right starting point
- Open the publisher’s game page for the current feature list and system requirements.
- Buy through the official store for your platform rather than a key reseller you cannot vet.
- Expect 60 test chambers mixing bridge physics with portals, gels and turrets, per the publisher.
