How to split the roles
When one of you plays more than the other: who takes which seat in Portal 2, and why.
Plan the solution and ping where portals go
Pings mark targets and timers without text or voice.
Follow the pings and experiment freely
A destroyed bot is rebuilt seconds later and co-op has infinite lives.
Skill-gap friendly · higher is easier
3out of 5
Death costs seconds, but both players must solve and play through every chamber.
General help only: a difficulty choice, drop-in/drop-out, quick respawn, per-player settings or turn-based pace. Both players still face the same core challenge.
Easy to coordinate · higher is easier
1out of 3 · Hard
Valve asks players to think cooperatively; pings exist to coordinate placement and timing.
Hard: constant talking, or one player sees or knows what the other needs.
The roles Same moves for both
Atlas and P-body have the same tools; each has its own portal colours.
Atlas Moderate
Moderate seat: puzzles and talking it through.
Places its own pair of portals and solves chambers with the partner.
- Puzzles
- Talking it through
- Timing
P-body Moderate
Moderate seat: puzzles and talking it through.
Places its own pair of portals and solves chambers with the partner.
- Puzzles
- Talking it through
- Timing
Help for the newer player
- Infinite lives; a destroyed bot is rebuilt in seconds.
If one of you fails: A destroyed bot is rebuilt seconds later; lives are infinite.
Ways to split the work
- Use the Timer ping to count down timed moves together.
- Ping instead of talking: it marks spots without text or voice.
- Failing is cheap: a destroyed bot is rebuilt seconds later.
