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.”

A0.886 Beta Build Released on Steam

We tried to get a couple of things into this build but failed, so they're for the next build. First is the (optional) level up skill tree for Adventure mode, second are several new weapon parts for the Creation Editor. At the end of this build, we ran into a few problems with AI pathfinding optimization, that's what caused the delay. The problem still persists in the form of frame rate drops when loading AI, we're going to fix that in the next build.

A lot of players have asked us about when we're moving forward with the story. Well, we're actually mainly focused on the story, it's just that there are so many moving parts and the story mode is the culmination of these parts. Once we have most of the AI and special events written completely, then story will go from start to finish without a hitch. The end part of the story needs new AI systems or they won't work (you know, the part about befriending or warring against...). Due to the AI being a bottleneck for our game, we've already put 3.5 programmers on this task.

For the next build, we're going to put in more animals, flying AI, better NPC AI, level up skill tree, updated battle/hit system, and perhaps an early form of the custom armor. Speaking of custom armor, here's a preview:

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
I've just recently started a single player storyline version of this game. Overall I have to say I am enjoying it. There is not much to not like. Sure, there is a slight grind collecting materials (if you've played MMO's like WoW, I don't think it's as painful as their grinds!!). While collecting materials however you're immersed in a vibrant world with creatures fighting between themselves for survival.

The UI is straight forward but I haven't started base building or item creation yet. The basic replicator usage to create 'recipe' items is very easy, and I like how you can click up and down through the layers of items you need to build up towards a more complex item - for example, you need gunpowder and copper to make bullets. But you have no gundpowder, simply click on the gunpowder Icon and suddenly you're looking at the gunpowder creation screen... how intuitive! There are a few tricks with the UI that had me briefly confused, such as 'do not have the inventory box open while trying to loot animal corpses or interact'.

The story line is easy enough to follow, and the quests are interesting enough. The side quests are optional but you can get a lot of handy stuff like the recipes you use in the replicator section. Buy the recipes in shops from NPC's, don't waste your meat (meat is money) on the actual item. Meat also can be converted to fat... fat plus charcoal equals gunpowder... you get the picture... A few tools like made of copper or iron, and suddenly you're collecting resources like a boss!

This game has some slight challenges, a sizeable world to explore, but most importantly it is thoroughly relaxing to play with it's intuitive gameplay and music...ok, so I have my music turned down but I haven't turned it off completely like I do in most games!

Early Access Review
Serously keen for this game to be great, Looks really good and prehaps could be, sadly as many other people said it is still in alpha. Updates have been far fewer and less added I sadly feel the game might not survive to come out of beta, idk if its funding or lack of devalopers either way both are achiveable if the devs can put thier mind to it. e.g. cruching a few weeks into just bug fixing to move the game to beta would boost numbers and sale a bit as well as bringing some hype to the game and hiring more devs their are plenty out there that would be keen for a learning experiece even for free (cough me cough). Any way good luck looking forward to hopefully posting a postive review for this in the future.

Early Access Review
I found the game to be quite bland. It has a variety of landscapes and creatures, but they seem to be slapped together with an algorithm that doesn't make much sense and can make worlds seem awkward.

Constructing anything seems needlessly complex, which makes producing anything not so much a challenge but a grinding task. Some may enjoy this but I find the cost/reward to be very imbalanced.

For a voxel based game I found digging to be far too awkward and time consuming, which led me to avoid digging where ever possible.

The vehicle construction is fun and I like the option to design your own weapons, too. I also enjoyed the variety of transport methods like jetpacks, helicopters and motorbikes.

Planet Explorers is mediocre and there are many games that do each element better, but perhaps few that combine them into a singular game.

The difference between this and every other open world crafting minecraft inspired game, is crafting your own weapons and vehicles. Makes this game stand out amongst others.
Looking forward to the game finishing devlopment (I hope... devs are active as of writing this)

Early Access Review
game is fail and falling out of the sky fast just like your escape pod at the start of the story this mission failed and your its falling out of the sky burning. unlike in the story theres nothing left after the crash so dont jump on this ship. also with a name like Planet Explorers you would think maybe more than one planet but theres one and its boring story mode is broken free rome is insta over ether you can find all the resources you need(in 30min or less) or you cant find anything. also you are likely to spawn in a tree so high that theres no way to get down or in another spot that makes you traped this hapens a lot. theres a 2d game just like this but better and its bound to get done. tho people are bashing it a lot but its a star of a game.
