Monsters vs Aliens

For this achievement you need to collect a hundred thousand DNA particles, now luckily this achievement is accumulative and will count any DNA particles that you've spent in the lab. Also, you'll get this while working toward; Solution for Never Say Enough In Monsters vs Aliens

From the main menu select; "Scenes" and then select; "23: More Aliens".

You play through the level as normal until you reach a certain point, at this point a machine will continually spawn enemies until you destroy it, luckily for us you also have a machine that can kill these enemies with ease. Just don't destroy the machine that is spawning them and you can keep racking up the DNA particles here.

I've linked in a video which will show you what to do!

This will just come naturally, destroy every object and kill enemies and your home free.

For this you must collect a ton of the DNA dots spread all over the maps, there are a ton of them and you most likely collect the 100,000 way before the game is over.
