The Banehammer is a super-heavy vehicle used by the Imperium, a close cousin to the venerable Shadowsword and Baneblade. It is unknown when the Banehammer was first created but it has had much use, especially during the recent Tyrannic Wars. The vehicle is primarily used by Imperial Guard commanders to halt massed enemy advances.
The Banehammer replaces the Baneblade’s Battle Cannon with a Tremor Cannon, which launches projectiles which bury themselves and detonate only after traveling some distance. On detonation, the shell releases a huge shock wave, liquefying the nearby ground and forcing enemy infantry and vehicles to literally crawl their way through or risk the consequences.
