How to unlock the Necro Flambé achievement in Dead Space 2 - Definitive Guide
I found the easiest way to get this was killing infants (not the exploding babies though) and parasites as the Flamethrower is fairly short range but useful against swarms. Cysts DON'T count towards the achievement. Use primary fire rather than secondary as secondary is not especially effective for the amount of ammo it uses.
It can also be effective in one on one situations with larger enemies eg Slashers as flaming them tends to halt their movement towards you.
There is a counter in the "achievements" menu that you can access by hitting start. Note that progress towards the achievement is recorded at checkpoints so hitting "checkpoint restart" will wipe any progress since the last checkpoint, so you can't just find a good spot, spam it, and then restart the checkpoint.
I haven't yet tested whether saving a game, killing enemies, making it to a checkpoint, then reloading the save and repeating the section would work. Edit: NorrisMM has suggested this will not work either (i.e. you need to do it the hard way!).
Edit: If you're going to downvote, at least explain why.
The Flame-Thrower Schematic can be found in Chapter 6, at the end of the "school' area, after the giant necromorph attack on the gymnasium stage. After being attacked by the Crawlers and Pack in the gym, exit through the door on the right (if you are facing the bleachers). Follow the hallway down and to the left. The room on the right, where the woman was hugging the Crawler, will contain the schematic. Purchase the flame-thrower at the next store and start racking up kills. This weapon burns through fuel quickly so I recommend using it during encounters with multiple necromorphs. Always keep extra fuel canisters on reserve.
Once you have acquired the Flamethrower schematic in Chapter 6 and bought the weapon, use this to burn 50 enemies. You should target weaker enemies like The Pack as the flamethrower tends to eat alot of ammo very quickly.
I got a trophy for my first playthrough without even bothering.
