Step 1: Classic mode

In this Mode you have to reach a score of 100,000. This should easily be doable without any detailed explanation. While trying to reach 100k Points kill one big orange enemy and hit a grey enemy (check Image below). Once you reached 100K points just let the enemies kill you. The Achievements will unlock after you died.




Tipp: Kill the big orange enemy first. This will give you a stronger weapon and makes it faster and easier to reach the 100k Points

Step 2: Time attack

Start the game mode "Time Attack" and reach 10k Points. You will have more enough time to reach 10k. Once u reached 10k simply let the enemies kill you and the achievement will unlock.

Step 3: Hardcore Mode

Reach 1,000 Points in hardcore mode. Self-explanatory. Just die after you reached 1000 points and the achievement will unlock.

Step 4: Challenges

Choose mode "Challenges" and clear 12 out of 30 Challenges. I recommend doing the first 12 to make it much easier.
