Party size and server size are different
Official materials describe co-op groups of up to four players defending the same path. The Roblox game record lists a server size of 20. Twenty is the instance cap, not a twenty-player squad and not a reason to stack twenty Reds. Voice chat and camera are marked unsupported on the game page.
Solo is enough for the first clears. Invite friends after you can place Red and read a skip vote alone. Four people skipping at different moments lose faster than one careful player.
Agree five things before wave one
- Who owns single-target, pierce, splash, and either boss damage or knockback.
- Which speed you will use until the line is stable. 2X while placing is enough.
- Who may call SKIP TO NEXT WAVE. In co-op the button counts votes. One player can still ruin a wave by voting while another is placing.
- Which player owns the entry stretch, which owns the bend, and which owns the tiles by the eggs.
- The abort rule: if health is falling fast, drop to 1X and stop skipping.
A friend who has not unlocked a bird cannot be assigned that bird. The 5, 7, and 12 slot locks are per player.
A four-player split that matches the printed roles
Early South Beach usually wants Red, Chuck, Bomb, and either Terence or Stella. With four players you cannot field all five specialties at once. Pick the four the current leak needs.
- Entry: one Red on the longest first stretch. Extra Reds on the same tile waste Gold.
- Straight: Chuck where pigs line up.
- Bend: Bomb where they clump.
- Eggs or heavy target: Stella if leaks reach the nest, Terence if one body will not die.
Call the zones out loud. Two players building on the same neighborhood spend two wallets on one angle.
Skip and speed etiquette
Healthy skip: UNITS ALIVE is under control, every role player has finished placing, then someone votes. Unhealthy skip: the vote fires during a Bomb placement. Anyone should be able to say hold once per wave without an argument.
Do not pull the lobby to 7X while a new teammate is still learning the arrows. Random fills may ignore the plan. If that happens, cover splash or the eggs yourself and assume duplicate damage will appear.
Each player still redeems angrybirdsarego on their own account. Sharing a lobby does not share the code reward.
After the clear
Storm The Beaches can be earned in co-op. It is still a full beach clear, not a single wave. Afterward, talk about who unlocks the missing role next so the group does not turn four experience tracks into four copies of the same bird.
If a run fails, change one thing: the zone that leaked, the role that was missing, or the skip that was early. Changing all three at once teaches nothing.
