This is a guide to help you obtain the Ursragna achievements: Completing the Juggernaut mission on Hard difficulty.
This is, by far, the easiest mission to obtain on Hard difficulty for one reason: a weapon stuck in a tube with nowhere to go but towards you! Here's how I did it:
1) Load up the BurnOGOTOS mech from your schematics.
Don't have this mech? Dispised Icon developed this schematic and posted it on the xbox360achievements.org forum. NOTE: ALL CREDIT GOES TO DISPISED ICON FOR THIS SCHEMATIC AND MECH DESIGN.
Legs: 047AN04 (Note: Do not equip anything but bi-ped legs)
Side: Holoferens or S02-001-EGA (Note: I had neither of these available and still managed without them)
For the BurnOGOTOS:
R. Arm: ER-0200
L. Arm: ER-0200
R. Back: OGOTOS
L. Back: OGOTOS
R. Hangar: None
L. Hangar: None
Set to AUTO
Focus your points on the following:
2) Load the mission and move back
Once the mission is loaded, immediately start to burn backwards while facing the door. Hit the LB and RB to bring up your OGOTOS and get ready to fire.
3) Open fire
Once the door is breached, start firing madly at the enemy. It'll just keep coming at a fairly slow pace. 4-5 shots should do it. If the enemy gets too close, just keep moving backwards in the centre of the tunnel. If you move to the sides, you may get caught against a beam.
4) Run like hell
Once you've stopped the enemy, it'll go into self-destruct mode. Move your ass by spinning around and flooring it down the tunnel. You won't have to go far, fortunately.
5) Happy Dance!
Achievement popped. 2.42 TA Ratio and 10 Gamerscore. Not too shabby!
