What the developers have to say:

“Planet Explorers is an open world RPG for its single player mode, as in there's a storyline with an ending. The game is in alpha, there will be bugs and strange things that we can't explain. Since it's an RPG, there will be more bugs than other games of the voxel type. Also due to the RPG nature, each main update will be spaced by about a month. But due to the decent size of our team, each update will contain a lot of content. We do listen very closely to our players, so you will have an opportunity to impact the direction of the game.”

About This Game

In Planet Explorers, it is the year 2287, one of the first colony ships sent out by Earth arrives at the planet Maria, in the Epsilon Indi Star System. During its landing sequence, something appears in front of the massive ship that causes it to lose control and crash into the planet. Some of the colonists survive in lifeboats, but what they find is an unforgiving land filled with creatures ready to outlast the visitors from Earth. Now the survivors must explorer, gather, build, create, fight, and ultimately, build a new home.

Game Modes

Planet Explorers will feature single and multiplayer modes.

In single player there are 3 distinct selections

  • Story Mode – Story mode is the main meat and bones of the game, it is the action-adventure-rpg-somewhat-4X segment, offering npcs, missions, colony building, farming, ranching, training, diplomacy, and of course, a storyline that you can follow or ignore. This story features a 17X8km world map with many unique character, landscapes, biomes, locations, and over 100 types of potential enemies. Even though we’ve made it seem like a very action oriented game in the trailers, in reality, players can choose to not fight so much as to just plant a farm, make some food, keep the colonists alive, negotiate with the sentient aliens, and defend the perimeter from the local life forms. That can still eventually arrive at the ending. And yes, there is an ending.

  • Adventure Mode – This mode is based on a procedural map generated from a seed. Currently, it comes in a 40X40 kilometer map. Players will be able to complete random missions, defeat bosses, and explore different landscapes in the mode and eventually be able to setup conditions that they want to play (such as tower defense or attack an alien camp). This mode will also feature survival gameplay. The randomization in this mode will eventually pull in player made objects and locations so that a world will always feature something new and unique.

  • Build Mode – In this mode, there are no enemies and an infinite amount of building material. It also currently comes in a 40X40km map. Players will be able to build whatever they want in this mode, including everything in the Creations Editor. Think of this as the perfect testing ground to test everything you build. Or…it’s your place to build your garden without ever worrying about the pesky aliens.

Multiplayer allows Local Area Network and player hosted servers. It features several modes but some are still on the drawing board or going through technical trials so the final result is still in flux. Players playing multiplayer should be able to bring at least one of their created objects into multiplayer games, be it a sword, gun, or vehicle.

  • Coop – Coop comes in many selections, such as adventure mode, tower defense mode, build mode, etc. This is pretty much an open world sandbox with a max of 32 players (this number still needs to be stress tested).

  • Versus – This mode allows teams of up to 16 players to battle against 16 players from another team. We allow full terrain manipulation in this mode. Currently, it's a point based system where one team wins if they reach a certain point level based on kills, built objects, resources mined, etc.

Early Access Review
At this point I am really concerned as to whether or not this game is even going to be completed. I've seen very little communication from the dev(s) in terms of progress or what exactly is hindering their progress, and the game page hasn't been substantially updated in months. Compared to some other early access steam games, this one seems to be dead in the water. When communication starts to die off like this I think everyone can agree it's almost aways a bad sign.

I've played roughly 40 hours at this point, and while not bad, there isn't very much to do once you've mastered the creation system. It's got cool concept for story, but then the main quest is full of glitches and at times those glitches are game breaking, so you can't even really experience the story.

If you do decide to buy it, buy it massively discounted and be prepared to join the rest of us in limbo

Early Access Review
Epic game, lots of fun if you like building games. For $24.95, even at full price this game is well worth the value. The developers have made good on many of their promises, though they may have set their own bar too high. As it stands, if this game never got another update I feel like a certainly got my moneys worth - much better than many AAA games that costs $49 or $59 on Steam. No Man's Sky will have a lot more stuff to do (a similar game on the horizon), but it will also be a $60 game. ;)

So a couple points about Planet Explorers:

Build Tools ROCK! Love how easy it is to just pull and drag out whole walls, columns, floors you name it. What might take a few days in a game like Minecraft to build you can get done in 1 day since the tools make building both faster and more fun. The barrier to entry in regards to building your first castle right from the start is almost none.

Exploration is pretty cool. You can walk around for hours discovering new stuff, new mobs, locating hard to find resources. If you like to just explore and see what the world has to offer, this is a good game to do it in.

Smooth Voxel epicness! No more Minecraft cube clone with this game.

Combat is OK. It could use a little more fine tuning obviously, but it is there, it works and plenty of weapons to craft to take down both standard enemies and bosses. Yep, it has bosses and they are HUGE and dangerous. ;)

Colonies and multiplayer. Multiplayer just makes it great - team with friends, load up a previously worked on world and work on building your empire together. I currently play this with two other friends and we always have fun.

Active developers. It is a small team so what you can expect for a game of this complexity? As I stated before, in it's current state, $24.95 is a steal for how many features are in this game. If it never got another update I would be fine. That being said, the developers, while sometimes a little slow, stay on top of the project and continue to work on stuff and make it better and bigger.

In conclusion, with the transition to Unity 5 an already great looking game just got even better looking. Don't expect lightening quick updates and constant patches every couple weeks or month - and honestly, this game doesn't need it. It is stable, it is fun and offers something differnt from all the cube based Minecraft clones out there.

Early Access Review
This game seemed to have a lot of potential. I was really curious as to where it might go, when I bought it nearly a year ago. I was waiting a few promises made by the devs, such as more of the neat stuff in story mode made available in adventure mode (with friends) before buying it for other people to play with me.

But since then, I've just seen one deadline after another pass by. Frankly, the devs are starting to seem disorganized and incompetent. I don't know what's going on over there. I would not buy this game until at the very least, the devs managed to finally finish 0.9, and see where the game stands then. I wouldn't be surprised if even more features get pulled from 0.9 before they release it.

Early Access Review
Not really pleased with my experience whatsoever, for a number of reasons:

-There is no feature in the game that currently feels polished, the voxel terrain, the character/creature models, items, at best the animations are mediocre and everything feels placeholder
-The only selling point is the ISO designer, of which you'll soon realise that there's nothing else much that makes the game worth playing
-The campaign is unengaging and repetitive
-The game hasn't been updated in too long a time for my liking, there is no sense of progress and to be honest I can see the developers abandoning this
-Overpriced for such limited content, however it is going on sale more often nowadays (which is an indication of a number of things i.e. it's not selling very well)

It's like the game has been built around one functionality and that is the designer, without it, then you literally are playing the most generic open-world/sandbox/RPG out there.

This is just my personal opinion, I had expected more development by now considering I bought this around 1 and a half years ago, and it's still the same game pretty much. Look before you buy

Buys game during near-pre-alpha-but-not-exactly-day-0. Spends well over 15 hours using mainly the custom building features. 20/10 would build another supposedly air-tight sub only to drown.
