How to unlock the Crufts achievement in Ultratron - Definitive Guide
Save your money until after stage 5 (maybe buy 1 droid power), when you unlock your first Pet - Shooty Pet. Buy it for 2000.
Now try to pass the level without your pet being hit. If your pet gets hit and he's on the floor calling for help, just quit out to the main menu and when you press continue, you will start at the beginning of the same stage again. Now simply play through 10 level keeping in mind the above trick and you should get it at the end of stage 16. Try investing in "Auto Smarts", cheapest "Shields", "Smartbombs" and buy a "Droid Power" after the 1st boss.
P.S.: I quit out the game 2-3 times due to my pet being hit and still got the trophy for letting him survive.
This trophy is awarded for finishing ten levels in a row without having one of your pets take damage. You must have actually purchased a pet first to earn this trophy, doing ten levels in a row without a pet doesn't count.
This trophy is probably the most frustrating in the game if you try to do it later on after having purchased multiple pets. This is because the pets follow behind you in a train so they will easily get hit by bullets or moving enemies because you don't directly control them. Because of this it is easiest to do this trophy right at the beginning of the game with only one pet. Whether you do this your first run or restart after finishing everything else is up to personal preference but doing it as soon as possible in the game is easiest.
You can purchase your first pet at level 5 for $2,000 so it is recommended that you try to purchase it as soon as possible after level 5 or level 6. Once you have purchased it, you must make sure that it never gets hit by any bullets or enemies until you have earned the trophy. It is okay if you are hit and lose a shield/reset the multiplier but if your pet is hit it will ruin your run of 10 and you will have to start over. You should play the levels as safe as possible and not purchase any other pets until you have finished the 10 levels, as having more will only make it harder to keep them from getting hit.
If you are doing this and get hit during a level you can pause the game and quit to the main menu then when you select play again, choose to continue and it will start you at the start of the last round you were on again and will not nullify the trophy.
