You get this achievement for beating a mini-game (hacking) level without losing any health.
It may seem a little difficult after playing some of the harder hacking levels found later in the game - but it can be done relatively easily.
I got this achievement on the first hacking mini-game.
Which you can replay in the Mini-Games section, on the main-menu when you start the game up.
- The first mini-game is easier than later hacking levels as the enemies can't shoot you.
- The only way you can lose health is if the enemies hit you, so take them out from a distance.
- Use the power-ups effectively, try to save the yellow 'mine/vortex type' power-ups, for the final stage of the hack as the first 2 stages are quite simple to get through.
It may take a couple of attempts, but once you get used to where the enemies spawn, you should be able to get this done pretty easily. :)
