Sledgehammer

The Sledgehammer is one of the 19 weapons available for use by players in Red Faction: Guerrilla.

Description
The hardened steel sledgehammer is a familiar sight to the thousands of prospectors working the mines of Mars. As such, it is also a useful weapon, since the EDF are unlike to consider it a significant threat. The Sledgehammer is capable of inflicting moderate structural damage, which can be useful in creating entrances, exits, and vantage points. Additionally, the Sledgehammer can be used to eliminate targets silently.

The EDF doesn’t react immediately when you have this weapon out, so it can be used for silent (albeit messy) kills. Need a backdoor for an escape? Make a new one.

Part of what makes the sledgehammer so powerful is not just Alec Mason's strength, but the mass-multiplier servo motor that delivers 1000 pounds of kinetic force.

If the enter the code hardhitter in the extra menu the sledgehammer will get replaced by goldbreaker

Trivia

 * Despite the fact that EDF won't react to it during gameplay, in the beginning cutscene the EDF officer refers to it as a weapon, and is fearful of it.
