Piranha Games offers a new trailer from MechWarrior 5 Mercenaries showing off the kind of destruction to expect when their Mech game is released in December. Here's the official explanation:

While there has been damage of sorts featured in past MechWarrior games, none have extended the destructibility feature to the extent of MechWarrior 5: Mercenaries. And having played various builds of the game to date, I can attest that blowing shit up in a giant robot FEELS REALLY FREAKING GOOD.

TYPES OF DESTRUCTION:

• MECH DAMAGE: Mechs will take damage to various parts, including limbs – and depending on what has been damaged on your mech will vastly affect how you can perform in battle. If your leg is destroyed you may not have the stamina or speed to get back to your dropship in time, for example.
• ENVIRONMENT DAMAGE: Environments can cause damage as much as an environment can absorb damage. If you are on a hot planet and running a larger/quick-to-overhead mech build, you will be able to deal far less damage to your enemies. Additionally, in both urban and natural environments you will have the ability to use buildings, certain rock formations and trees as cover but all of it is destructible – so if getting at enemy mechs means taking down a skyscraper, THEN BY ALL MEANS…
• ENEMY AI DAMAGE: MechWarrior 5: Mercenaries will feature numerous forms of enemy AI infantry and combat vehicles and helicopters designed to defend and protect bases, forts, mines or resources. Taking them out will require precision aim and a penchant for knowing which types of ammo and weaponry work best to deal with smaller but deadly and hostile units.

MechWarrior 5: Mercenaries launches this December. It is the first single-player MechWarrior game in more than two decades. Featuring co-op, full modding support and a campaign with replayability in mind, you will navigate your band of rogue pilots and crew into one of the more feared, respected and coveted lance’s (unit) in the Inner Sphere.
