10 Pro Tips to Master Co-op in Portal 2 and Outsmart GLaDOS

1. Communicate Constantly

Use voice chat or the in-game ping system to share your plans. Say where you're placing your portal or what you need from your partner. Even simple callouts like "blue portal on that wall" save time.

2. Learn to Use Both Portals Independently

Each player has a blue and orange portal. Train yourself to think about both colors simultaneously. Often the solution requires one player to create a path while the other provides a second portal for momentum.

3. Master the Art of Flinging

Flinging is essential in co-op. Practice falling through a portal to gain speed. Coordinate with your partner so they position the exit portal to launch you toward a distant ledge or button.

4. Use the White Gel to Your Advantage

White gel allows portals on any surface. If a puzzle has white gel, coat a wall or floor to create new portal spots. Communicate where you've applied the gel so your partner knows where to shoot.

5. Hold Positions When Needed

Sometimes you need to stand on a button or hold a cube in place. Tell your partner: "I'll hold this, you go." Don't move until they say they're ready.

6. Think Vertically

Many puzzles require vertical thinking. Place one portal on the floor and another on the ceiling to gain height. Use angled surfaces to redirect momentum.

7. Use the Excursion Funnel Wisely

The blue and orange funnels can transport objects or players. Coordinate who rides which funnel and where to drop items. Sometimes one player must redirect the funnel while the other uses it.

8. Keep Track of Your Partner's Position

Always know where your partner is. If you lose sight, check the small indicator showing their location. This prevents accidental portal misplacement or falling into pits.

9. Practice Timing Together

Some puzzles require simultaneous actions, like both stepping on buttons at the same time. Count down: "3, 2, 1, go!" to sync your moves.

10. Don't Be Afraid to Reset

If you get stuck, use the reset button. It's better to start fresh than waste time. Use the time to discuss a new approach while respawning.

Remember: Portal 2 co-op is about teamwork and creativity. With these tips, you and your partner will conquer GLaDOS's tests in no time. Good luck!
