Mega Monster Truck Rally: Rampage Edition

Newest update: Clear Arena (2026-10-09)

• The stadium got a massive new pit arena where trucks can tear into each other in head-to-head chaos.
• Fans now panic and flee when the action gets too close — watch the crowd scatter as you rampage through.
• New monster tire obstacles litter the arena floor, giving you more stuff to crush and bounce off.

Earlier update: Gate Fence Tightened (2026-10-09)

• The catch fence now runs right up to the 1M gate's concrete edge instead of stopping short — trucks can't slip through the gap anymore.

Earlier update: Fresh Show Start (2026-10-09)

• Hit R to reset the welcome card and see the intro again — perfect for new squad members rolling in late.
• The catch fence now stops clear of the 1M gate, so nothing tears off in that opening.
• Press Enter on the welcome card to jump straight into the action.

Earlier update: Break Free (2026-10-09)

• The grandstand's back wall now stands just 1 meter tall—drive straight out over the crowd and into the city beyond.
• Jumbotrons now broadcast a live chopper feed that tracks rampaging trucks with a tight, cinematic zoom.
• The arena's edge is no longer a barrier—your rampage can escape the stadium and tear through the streets.

Earlier update: Smooth Cams & Clean Crashes (2026-10-09)

• Chopper cam is locked in and smooth, no more wobble.
• Regular cam is steadier when you pan at speed and turn down new city streets.
• No more player avatars: your truck is you.
• Truck headlights glow instead of casting beams.
• City light poles snap and fall the way the parking lot poles do.
• Torn arena fence panels clear out fast so they don't jam your tires.
• Smoother driving through the city overall.
