Rise of the Kasai

This trophy might seem daunting but is mostly straightforward.

• As levels progress taking out enemies is usually required in order to exit an area so sneaking or speeding to the end of an entire level, does not appear to be an option.
• This means you need to let your partner do all of the work and they cannot be killed.
• Stick close to your partner and press to defend them. This gets enemies off of them and on to you. Many fights your partner may be able to handle solo but some can get close.
• Use the Wimpy Enemies cheat to enable your partner in taking enemies out quickly.

Personally, I chose to complete the first level this way. The first two areas you have to progress with your partner but area three actually lets you sprint to the end to open the gate and exit immediately. The final area four is simple for your partner to handle alone. If successful in the requirements, the trophy will unlock once the cut-scene has concluded and the "Do you want to save?" screen appears.
