NFS Underground at Home? Impressions from the Heatwarped Demo

The vibe is right. The handling isn't yet.

  • Primary Subject: Heatwarped (free Steam demo, full game unreleased)
  • Key Update: Sealime's demo recreates the look and feel of Need for Speed Underground, but its brake-to-drift handling is too slippery for grip racing.

  • Quick Answer: Heatwarped's demo nails the look and speed of Need for Speed Underground, but its slippery brake-to-drift handling isn't there yet.

Heatwarped looks more like Need for Speed: Underground than any game I've touched since the originals.

It took one corner in the free Steam demo to learn that it doesn't drive like it.

A City Pulled Straight Out of 2004

Heatwarped comes from indie studio Sealime, and the demo drops you into a slice of Ratfield, a fictional city built around an underground racing scene. They say imitation is the sincerest form of flattery, and this really is basically Underground.

The holographic event circles on the road and the icons dotting the map look lifted straight from 2004. So does the PDA that handles your messages and navigation.

Diegetic UI like that fits this genre perfectly, because it sells the fantasy of a scene that exists whether or not you're racing. This game wears its influences on its sleeve.

The one dead giveaway is the car. Nothing here is licensed, so the single car the demo hands you is a fictional model rather than a Skyline or an RX-7.

For an indie team with a demo out and no release date, that is an easy caveat to accept. What fascinates me more is the look itself.

Most retro indie games reach for chunky pixels. Heatwarped goes after a newer kind of retro, the soft, over-processed sheen of a PlayStation 2 racer at night, and the Steam page even splits its graphics settings into "Authentic" and "Enhanced" modes.

Seeing that treated as a period style put things in perspective for me. Underground and Underground 2 are more than two decades old now.

The Sense of Speed Lands Immediately

I came into the demo straight off a Forza run, where 200mph felt like nothing at all. In Heatwarped, 100 to 120mph is enough to warp the world around you.

Neon smears into heavy lines at the edge of the screen while the post-processing leans in hard, and the city starts to feel like it's melting past the windows.

Whatever else needs work, Sealime already understands how speed should feel in this kind of game.

Brake-to-Drift on Ice

Then there is the driving, and Heatwarped drives very oddly.

The Black Box era of Need for Speed leaned heavily on grip racing. Drift events were the exception, running on their own separate handling.

I can see the resemblance to those drift events here, and in that mode the game makes sense. In the open world and the regular races, it feels wrong.

Heatwarped uses brake-to-drift, and it doesn't get it quite right. I'm Filipino, so I've never driven on ice, but I imagine this is what it would feel like.

The car is so slippery, and it lacks the control that Need for Speed always seemed to give you when the back end stepped out (except in the 2015 title, because that was HELL.)

I think brake-to-drift was perfected in Hot Pursuit and Rivals, and both games had maps built around it. Heatwarped clearly knows this, because its corners are wider to accommodate the slide.

Even with the extra room, the car still feels like it's skating across the road.

Shortcuts That Cost More Than They Save

The demo covers drift, sprint, time trial, and circuit events, a classic selection, and a good spread of shortcuts to find along the way. Taking them is another matter.

Destruction in the environment is incredibly inconsistent. Some shortcuts are lined with small trees I expected to smash through, and hitting them still cost me a huge chunk of speed.

Streetlamps and barriers do the same, and they knock the car out of control on top of it.

It could be a deliberate choice to reward precision, or I've simply been spoiled by the newer Need for Speed games, where clipping a lamppost barely registers.

Heatwarped might just exist on its own terms here, but right now a shortcut rarely feels worth the risk.

A Garage With No Manufacturers to Answer To

The garage is already impressive. It isn't quite Autosculpt, but I was able to turn my car into something that felt like mine.

The lack of licensing actually helps here. Nobody has to ask a manufacturer's permission before bolting something ridiculous onto a bumper, so your imagination can run wild.

What I Want From the Full Release

For all its faults, Unbound let you push each car's handling toward grip or toward drift.

I've always been a drift guy, but the Underground inspiration might lend itself better to grip racing, and giving players that choice would fix a lot of what feels off right now.

More cars are a given for a full release, so I won't dwell on it.

This next one might be divisive, but cop chases have always elevated street racing for me. That's Most Wanted territory rather than Underground, though, so I'd understand if Sealime leaves the police out on purpose.

Multiplayer is the big one. I don't need individual lobby races. Need for Speed Heat got the formula right by putting everyone in the same shared world, and a Ratfield full of other players would suit this city.

Steam currently lists Heatwarped as single-player only, but the official site promises face-offs against online opponents.

The Vibe Is There, the Handling Isn't Yet

Ratfield has the right mood, and the speed hits exactly as hard as it should. What it can't do yet is drive well, and in a racing game that's the part everything else rests on.

Heatwarped has no release date, which gives Sealime time to find the grip this city deserves. It stays on my wishlist until then.
