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.
