This achievement is rather simple, if not annoying because no one is playing online. To get this simply, play on the 'Den' level, and be on the blue team. Get together a boosting party, or this achievement is near impossible.
Set the match limit to 100 animus. The person trying to get the achievement, jump down and head left straight away. There is always an Alpha Werewolf there. Kill it, and go to the animus and fill it up. If you make sure none of the other 7 players get any kills, your one Alpha Werewolf kill will be the most kills. Repeat this 10 times for the achievement.
- Boosting Party, 8 or 6 people, doesn't matter.
- Blue team, only blue will ever get wins.
- 'Den' map.
- When you start, jump down, go left.
- Kill the Alpha Werewolf.
- Make sure no-one else in the match (blue or red team) gets any kills.
- The Alpha should have given you enough animus to fill up your teams generator.
- Fill up your teams generator.
- Rinse and repeat 10 times.
- Let all the other people in your boosting session get the achievement.
