If the solution doesn't help you, leave a reply saying how can I improve it! Which players will get the achievement? Only the player that logs into the start screen will receive the achievement. Additional players will have to log in their respective saves and play the campaign again.
But, according to Quarantane, both players can get the achievement now. I can't confirm that, so stay alert.
Aug. 2019: According to Rondund, the main profile will get the campaign achievement, while other players won't. But they will get the achievement for playing at every level. Is it possible to finish the game solo?
Short answer: yes, I did it. Not an easy trip in the last stages since recipes are unpredictable. Some levels seem unbalanced, but you can do it!TIP #1 - PLAYERS
Try to play with an even number of players.
It is easier
to play with 2 or 4 players.
Playing alone or with 3 players will be harder
.TIP #2 - CONTROLS
Remember to use LB or RB to exchange your characters, if playing solo. Use this to optimize tasks, such as leaving one chef cutting something while the other goes to pick an ingredient up. Also, learn to use DASH
and win some time whenever you can.TIP #3 - KITCHEN DYNAMIC
If you can spare some time, always have meat in the frying pan.TIP #4 - SHOULD I TRY TO GUESS THE RECIPE?
Overall, there are two types of strategies for the levels:
(1) keep up with the good pace and organization: if, at a burger kitchen, you should always have meat in the frying pan and use your spare time to wash the dishes, mount the bread over them, etc.
(2) make little bets, gamble the recipes to come, as I had to do in 6-4
. When your kitchen accepts diverse orders or you have to change the rooms, then bet and try to guess a plate. Sometimes it will be just a lettuce salad, other times it will be a burrito.
I had trouble especially with level 6-4. After a while, I knew the level's layout and could keep the mess to a minimum. This one was one of those where I made bets.
