It's the end of the game. There's a dead woman across the lake, a dead deer, and a dead zombie woman. My cabin is a burned out husk. And here I am, naked, in a steam-filled sauna. Good times.
Final boss: Pull into the far left lane (incoming side) and you'll build nitro while you drive. Boost up next to the left hatch and jump on to destroy it (you'll bounce back into your car). Wait for beams to die down and the median to be open, and pull over to the far right lane. Boost up next to the right hand hatch and jump. If the right lane ends before you can do it, pull back into the oncoming lane and dodge lasers until you have another shot at the far right lane. Once the center hatch appears, wait for the middle lane to open up (you can't do it when there's a grass median) and boost up to jump on the center hatch. You can steer the ship as it goes down.
I love this game, but every now and then the unit AI can be pretty annoying. If I load up on Samurai because I know my opponent is fielding lots of vehicles, I don't want them to spend half the game running from infantry unit to infantry unit like they've got ADHD. They can kill infantry when the tanks and walkers are gone.
