Just me or is this a bit cynical? Don't get me wrong, I'm sure the gameplay is fun and everything. Just the concept makes me really uneasy, especially as I have a friend who's house was destroyed recently in war...

I think it’s the particular design choice of leaving emoji on the rubble you destroyed, with options like a skull, fire and so on.

The Call of Duty series gives a much more detailed view of the battlefield, with a lot more blood, and it doesn’t get a reputation for being cynical because it doesn’t force your hand with a choice that feels like mockery of the situation. This game’s emoji defaults slightly do, whether it was intentional or not.

I think it's fun, not cynical at all. I'm sure if my close one was shot, I'd be uneasy playing call of duty, and so on.

I'm sorry for your friend.

I'm surprised by the comments defending this, I also think it's in poor taste. I wouldn't say cynical, in my opinion it's worse than that, it's too real.

If it makes you feel any better tanks are almost useless now in modern war.

They can't at all compete with some off the shelf kids toy costing $30 with a HEAT round attached. The cost differential here with a 35 million euro tank is beyond pale.

This kind of outrage takes away from things that are actually distasteful and cynical. Conflating unproblematic things with actual harmful things is a you problem. Policing tone, while people are actually dying out there, is more cynical that this game. The only outcome here is there you guys feel better about yourself.

Having a negative opinion is not policing. If you want to spend your free time simulating destruction, that is really your thing. It's common entertainment. It doesn't mean others can't share a different perspective on it.

I don't think that quite makes sense. Sometimes it's useful to point out/shame unsettling things that happen in society, even if it doesn't directly cause harm.

I wouldn't say so, since shooting at mini tanks and buildings that look like cardboard on a gray street map doesn't seem connected to real events.

That said, I did not find the game fun. It was laggy, UI elements seemed a bit sloppy and cut off, and the purpose of buttons wasn't very clear. Also, I saw mostly brown tiles rather than buildings, maybe it was already all destroyed.

Thanks for the honest feedback. The lag was the server struggling with today's crowd, and I've shipped fixes for it over the last hour. The brown tiles are rubble from earlier players. Pick a city further away and you'll find it untouched.

Not just you. With a fourth of the world in an actual war, it doesn’t sit well with many of us.

That said, whoever made it might not be thinking about that. A kid could vibecode a game these days. I wouldn’t hold it against them.

Moreover, many AAA games glamorize war (Call of Duty, Far Cry, Battlefield…) or crime (GTA, Red Dead Redemption, Payday, Hitman…).

I think it's rather poor taste to code something like this. Usually when buildings or other things are destroyed in movies or even a game, it's to tell some kind of story. In a way telling the story brings the justification because the destruction in the story is usually counterbalanced by someone trying to stop it, which brings the story to the level of good being done.

This is just wanton destruction and has nothing good in it.

I mean, technically, Blast Corps had a story (you needed to pave the way for a runaway nuclear missle to not crash and explode or something), but then you'd get medals for thoroughly destroying everything anyway, because really it was about knocking down buildings and the "story" was a silly pretense. And it was great.

Rampage and its sequels were pretty much also just "destroy buildings, the game," and also great.

My kids enjoy building with tiles and then knocking it down.

If your friend would be willing to share their thoughts, I’m interested in learning. Of course, if they don’t want to share or you think it would be disrespectful to even ask, don’t. I’m just thinking the perspective of such people should not be ignored.

I'm really sorry about your friend's home. I never meant it that way. It started as just a 3D map that you could drive around. Then I added collisions, then a tank, and it grew into a game from there. None of it came from anything in real life. But I understand why it feels uneasy when war is real for people you know.

Thank you! You're right, it was buried behind a tiny ⓘ. Fixed now, so the OpenStreetMap credit is always visible in-game and on the home screen.

Fun idea but horribly laggy. Just driving down a street and I would get bounced back constantly and make very little progress. Ping was showing up as much as 5000ms
reply
n4ze3m 4 hours ago
sorry, that's on me! Way more people showed up than I expected and the server couldn't keep up. When it falls behind it drops your inputs and yanks your tank back, so that's the bouncing. I found the culprit (collision checks looking at way too many buildings)

For US addresses, can you include the state in the search? It's common for the same city name to be reused. For example: Dallas North Carolina (small town) vs Dallas Texas (metropolis)

It keeps saying "Your connection dropped. Let’s get you back out there." after a few seconds, then returns me to my spawn point. I don't see any bad HTTP status codes in the network tab

Can you make it a little more resilient on Wifi + 4G? I would really like to try this, it seems fun

Also, incorporating elevation data would also be really cool

Nice! Are tanks spawned at the last picked location? I picked my hometown as I wanted to demolish a friend's house, and I was surprised to find 2 tanks there (it's a random small city in Europe).

I also have the bug where it keeps respawning me to the starting point after ~30 seconds

They're real players, no bots! The 30-second reset was a connection bug, fixed now.

about 7500 buildings have been destroyed since this was posted. most are houses, shops, restaurants and offices. I'll add a stats page soon so anyone can see it.

I am genuinely interested in the opinions of people who live in or fled war-torn countries. Would they find this in poor taste? That it trivialises ongoing struggles? Have they tried looking into their own cities? Do they not care? Do they think this is somehow useful? Does it surface memories? Are they more bothered by the execution?

Of course, we’d need more than one or two data points. If you know someone (or are you yourself) in that situation, I’d welcome learning your thoughts. No judgement or ulterior motive, just looking to understand another perspective.

Edit: And, of course, the downvotes are already coming. Don’t know why I bother with this community anymore. Call for exploiting and exterminating other people (I’m not talking about this submission) and you are celebrated; but try to be empathetic and learn about others, no sirree, can’t have that, that’s a grave offence to the great hacker blowhards who frequent the big AI News network. This community has become putrid.
