VG247 has spoken with lead level designer at Avalanche Andreas Gschwari. He's talked us through the vehicle customisation options and how these will impact on gameplay. We've also had a good look at some of the insane vehicular combat options.
He told us that there will be "millions" of car customisation combinations. Each part will affect car physics, speed, weight, and more, which means decisions will have to be thought-out and considered so that you don't end up at a disadvantage when you go into battle. Upgrades are earned by salvaging scrap - much of this will be earned through key missions and taking on enemy convoys.
Survivor strongholds in different areas of the world specialise in different parts. For example we saw a guy called Jeet who specialised in ramming grills. The changes and parts that can be added to vehicles were too many to count. You can change tyres, bodywork, engines, suspension, and many more. It's like a post-apocalyptic Pimp My Ride.
We saw a grappling hook (think Just Cause) being fired from cars to dynamically tear down sniper towers and gates. Everything was running on a PS4, and we're pleased to say it's all looking rather good.
One final note: the Max in the demo we saw came complete with Australian accent.
