Quantum Theory

Breech (15)
Clear The Womb on Hard

This achievement is related clearing Scene 0-2 on Hard difficulty either by completing the entire scene on hard or by playing the final checkpoint of the scene on hard.

To do the latter:
- Select Story
- Select Scene and then select Scene 0-2 The Womb
- Select Easy Difficulty - Whilst navigating the Scene pick up the Bloodcleaver (Claw Gun).
- Complete the Scene, but do not start up the next Scene
- Quit to dashboard and boot up the game
- Select Story
- Select Continue
- Select Hard Difficulty

The easiest way to complete the Scene is to use the Bloodcleaver as mêlée weapon (it does a greater damage) and circle the seed mêléeing the enemies whilst the teammates are setting the charge. This is much easier that trying to shoot because:
A) The enemies move and the aiming can be problematic
B) It dispatches the enemies faster as it a 1 or 2 hit kill, whilst many of the projectile weapons require multiple hits
C) There is no need to reload

Note - It is not necessary to complete the entire game on hard to get the ‘Death & Rebirth’ Achievement only the final checkpoints of Scenes 2, 6, 9, 0-2, 12 and 13.
