Faster Than Fire achievement in Contract With The Devil is a tricky one because of three reasons.

• Items combinations - you have to look for items to combine them and then click on the combined items. It takes more time than it is necessairy because of the next point...
  
• Animation delay - it's a big one. Upon clicking on a hidden object, you are locked for a few seconds until the animation ends, then you can click on the next item
  
• Inconsistent hitboxes - that's pretty self explanatory

There's, however, a pretty easy way to obtain the achievement. It might seem a bit of a cheating but that's nothing compared to SAM users. Anyways, here goes...

Yup, it's simple as that. Locate most of the items, then at a few left - leave the puzzle, then go back and click on the remaining items. The timer resets whenever you re-enter the HOG scene so it's actually quite easy achievement. Just not everyone might realise that.
