Again, it's not an indie game, it's been in development for 3 years. and it seems rather ambitious.

Preview From Destructoid :

The Tomorrow Children is a sing-player experience set in an open world. It's a network-based game where all players have a shared purpose. So you'll play alongside each other, and you'll have a common goal, but you're all doing your own thing.

That's not the weird part. The weird part is that the game is set in a future divergent from our own, in what looks like the late 1960s in Soviet Russia. The players are projected clones that look like wooden puppets from Eastern Block countries like the Czech Republic. Among the oddities there are Matryoshka Dolls, shiny Godzilla-like beats, giant metallic spiders, and jetpacks. Yeah.

In this branch of the future, a Soviet scientific experiment went wrong and and almost destroyed the world. Ruined it. The player works as a projected clone in this world, mining resources to rebuild, working to restore the real humanity.

The game is split into two areas: towns and islands. The islands have resources to be mined to help towns operate, thrive, and eventually grow. These islands all represent something from mankind's past -- the first one we saw was a giant pink head with missiles planted around it.

Players can climb these islands and use the tools in their inventory to mine and explore these islands. We watched on as Cuthbert dug a staircase into the face, eventually working his way into an established cave where other players mined alongside him. Resources are gathered and treasures are found during this mining.

There are Matryoshka Dolls that can be gathered from these islands and brought back to town. They represent missing members of humanity, and they can be turned back into humans. Finding these goes towards the ultimate goal of the game -- to restore humanity.

Cars and other craft can be communal resources, though there are also public transportation options like buses. He drove the hover car over a shiny white landscape into town. This town was sparse, containing only a few buildings, trees, and NPCs.

In town, you'll help build, grow, and sometimes repair the structures there, with the ultimate goal of expanding the town. All others playing will do this alongside you. We watched on as Cuthbert used some of the communal mined resources to repair attacked buildings. While doing this, a giant monster approached the town from the distance. It looked like crystal-covered, metallic space Godzilla. Other players joined Cuthbert in manning turrets to take it down. And when the beast finally fell, it became mineable, just like the islands.

Every action performed in the game -- mining, repairing, carrying, dropping, throwing -- is recorded and tracked. Checking into a town's labor office gives you access to a daily report. Actions earn tribute points and ration awards. The tribute points go toward your standing and how the community views the player, while the rations, or Russian Coupons, can be used to by perks, better items, and more.

Some of the content will be manually designed while other parts will be procedurally generated. There are plans to let players work up the ranks. Every town will have a mayor. Elections will let players pick this mayor, which will let them shape the city.

Here’s a summary of the information he provided about the game ( from dualshocker):

• The Tomorrow Children uses a new lighting technology named Cascaded Voxel Cone Ray Tracing, which allows to simulate lighting in real time, and uses actual real reflections, and not screen space reflections like most games.
• The trailer released tomorrow was completely in-game.
• The game is set in Soviet Russia after an experiment has gone terribly wrong, almost completely wiping out humanity.
• The players are clones working under a mysterious deus ex machina named “The Administrator.”
• The game is online, and the developers plan to have between 50 and 100 players playing together in the same town.
• The game’s world is made by the town and by the island, where players go to labor and fight monsters.
• Every thhing you do gets recognized by the labor office, and you get recognition point that you can use for perks and new weapons, improving your status in the community.
• When enemy creaqtures attack,players collaborate to repel them. When they are dead, they can be mined to find crystals (used to expand the town) or matrioskas that contain humans who can be restored.
• When the monsters manage to destriy a building of the town, players can chip in to rebuild it.
• Resourced mined are a mix of procedurally generated and manually placed.
• There’s a voting system planned, where players can participate to an election to become mayor of the town. Bribes are also involved to improve the odds.

This sounds so good and innovative

When I saw it, I didn't really know what to think about it, after reading previews it sounds really cool and fresh, looking very much forward to it. But the trailer didn't get the message across.

sounds great..

...but there are no guns or blood therefore it is an indie game.

It also doesn't look realistic, which means it's even more indie

sounds fucking awesome. i would buy this right now if it were released! i want this!

Well, Hotline Miami has blood and guns :p

And is that indie? Nope

Indeed, this logic seems right, now i understand why Read At Dawn added gore in their game, it was only a small indie before that :

true but it also used pixel art. 

the definition of indie has a lot of "or" statements.
