Launch the boat | Chapter 13 - With the Tide DI Riptide Guide
Last update: 11 May 2016
Use one of new side passages to exit main area of laboratory, look for supplies and go upstairs.
Start exploring this area and eliminate zombies on your way. You'll meet another Wrestler - but he shouldn't be a challenge. Follow the path, reaching a small stairs. Use them and jump to the dock where you find a boat.
A net separates you from the boat, so you have to climb using crates shown on the screen above.
Look around and turn left to reach a console which descends the boat (screen above). Use it and watch a new cut scene with Frank Serpo.
