For this challenge, you have to deal a certain amount of damage with a different weapon specified for each stage of the challenge.
The weapons in the different stages will usually have something in common with each other, i.e they're all Assault Rifles, Explosive Weapons, etc.
For example, the stages can be:
- Stage 1: Deal damage with standard Assault Rifles to opponents (0/200)
- Stage 2: Deal damage with Burst Assault Rifles to opponents (0/200)
- Stage 3: Deal damage with Silenced Assault Rifles to opponents (0/200)
- Stage 1: Deal damage with Grenades to opponents
- Stage 2: Deal damage with Grenade Launchers to opponents
- Final Stage: Deal damage with Rocket Launchers to opponents
- 10 Battle Stars.
These are split amongst the various stages (for example 3 battlestars for first and second stages, and four battlestars for third stage)
- Damage does not have to be all in the same match.
- You can open the map while in game and go to the "Challenges" section to see what stage you are at, if you do not remember.
