How to unlock the Time is on my side achievement in Call of Juarez: The Cartel - Definitive Guide
You should get this during the campaign (particularly if you are playing on hard or make constant use of the CM), but if not, just load up your favourite level and repeatedly use CM after filling the meter. It will unlock relatively quickly.
Note: I did this with Evans, whom I found easiest to use with CM.
For this trophy you must first have your concentration meter filled by killing enemies. Killing enemies with headshots will fill the concentration meter more. Once you have filled the concentration meter, you can press to activate it and start slow-motion in which all enemies will be highlighted. Once you start the concentration mode you will see that it depletes over time until there is none left (meter will be blue once active). For every 5 kills you will get a blue icon on the bottom right corner of the screen showing “Time is on my side x/50”, which will tell you of your progress.
Build up concentration mode by getting kills, and activate it by pressing left on the D-Pad. This can be grinded out if a concentration mode is saved up until reaching a checkpoint, then activating and killing the enemies. Then reload checkpoint and repeat. However is not needed as you will be using this option very often during your playthroughs.
