Heavy Hitter is a Steam achievement in Retribution.
Getting it[]
This is probably the most painful TLS achievement to get. You must play the Anvil of Khorne map, where there are six (6) super units per each complete play-through:
- Wave 13: Swarmlord
- Wave 16: Battlewagon
- Wave 17: Avatar
- Wave 18: Great Unclean One
- Wave 19: Baneblade
- Wave 20: Land Raider
You must personally kill 25 of these. This means a minimum of five complete play-throughs assuming you beat wave 20 each time and manage to avoid your teammates killing any super units. Since dying before wave 20 or not getting the final blow on a super is fairly common, 10 or more play-throughs is probably a more realistic estimate.
