Appendix - Challenges - Enemy Combat category | Challenges

Blood Trial

Requirements: Kill 10 guards (Grunts).

Comments: Piece of cake, especially since you won't have to perform any other moves while killing them.

Rewards: New challenge, Hip Shot.

Slayer

Requirements: Kill 25 guards (Grunts).

Comments: This is also a very easy assignment. Keep attacking the guards using your favorite moves.

Reward: New challenge.

Headshot Bonanza

Requirements: Kill 50 guards with headshots.

Comments: I would recommend that you start completing this objective right away. Each time you attack a new group aim at the heads of your opponents, especially when you're going after single guards.

Nemesis

Requirements: Kill 350 guards (Grunts).

Requirements: I guess you won't be surprised to hear that you'll spend a lot of time trying to complete this objective. It shouldn't be a problem as long as you'll explore all levels and kill anyone you encounter. You should be done with this task while still playing the second act of the game.

The Bold Approach!

Requirements: Damage a Biomech with a Death from Above attack.

Comments: I would strongly recommend that you fulfill this assignment during your first encounter with the Biomechs. Attack the mech located below. that you must only damage it, not destroy it.

Reward: New challenge.

Fair Fight!

Requirements: Defeat a single Biomech.

Comments: This is a very easy assignment, because sooner or later you'll have to defeat a Biomech in order to advance with the mission.

Rewards: New challenge, Faster Reload 1.

Cracker

Requirements: Defeat five Biomechs.

Comments: Another easy assignment, because you'll have to defeat a lot more than five Biomechs during the course of an entire game.

Reward: New challenge.

Anti-Air Measures!

Requirements: Destroy a single Polycraft.

Comments: You can follow the instructions given to you by the game (zip kick attacks) or you can use your firearms, preferably a rocket launcher.

Rewards: New challenge, Hollow Point.

Torn Into Pieces

Requirements: Destroy a Polycraft while still in the air.

Comments: Easier than it sounds. You can complete two challenges (this one and Anti-Air Measures!) at the same time by attacking the first Polycraft with zip kicks.

Poly Cruncher

Requirements: Destroy 10 Polycrafts.

Comments: It shouldn't be a problem, as long as you don't avoid any Polycrafts. There are more of them to be found during the course of the game.

Biomech Sweeper

Requirements: Defeat 15 Biomechs.

Comments: This is also an easy challenge, especially since you won't be allowed to avoid any mechs. Also - notice that you're starting with five destroyed biomechs from the previous assignment from this group (Cracker).

Spence is in the Air

Requirements: Destroy a Polycraft using the adrenaline move (finisher).

Comments: Make sure that your adrenaline bar is fully loaded. Attach yourself to a flying machine and perform a "fatality" by pressing Y+B.

Come Out and Play

Requirements: Destroy a Biomech using the adrenaline move (finisher).

Comments: Similar challenge to Spence is in the Air. Stun the mech, attach yourself to it by pressing the A button and perform an adrenaline move by pressing Y+B buttons.

Reward: Medium Armor.
