Get instant access and start playing; get involved with this game as it develops.

Note: This Early Access game is not complete and may or may not change further. If you are not excited to play this game in its current state, then you should wait to see if the game progresses further in development. Learn more

What the developers have to say:

Why Early Access?

“As a small team, Early Access is a great way for us to... well... get the game into your hands early! We'll be able to get important gameplay feedback to make sure it's as fun as it can be, and at the same time polish any rough edges, add much more content, and get the game ready for final launch!”

Approximately how long will this game be in Early Access?

“It will be in Early Access until we're ready to release it. We're anticipating at least a few months.”

How is the full version planned to differ from the Early Access version?

“The full version will have much more content, more skills, additional missions, new monsters, etc. We also expect to get further feedback during Early Access that will help us determine what you want to see in the final game.”

What is the current state of the Early Access version?

“Intel HD Graphics - NOT SUPPORTED
Single-player mode is not yet available in Early Access, but will be added for the final launch.

Stability and bugs: There are some rough edges and the game may crash on occasion. However, it's already very playable thanks to early alpha testing, and we're absolutely looking for your feedback to make sure it's as good as it can be. We're very passionate and will be online pretty much 24/7 to gather any concerns or bug reports you have, in order to fix the problems and update the game as quickly as possible.

Gameplay content: There are several different game modes available already to keep you entertained. Most of the skills are done, and we're working on adding more throughout Early Access. You can advance through the full 25 ranks in each of the 8 playable classes, though there's still more work to be done on each class. If story is your thing, there are two primary mission storylines with four missions each, along with numerous bosses and lots of enemies. Most of the weapons and powerups have also been implemented. Needless to say, we feel there's already a lot of content to enjoy!

We really love this game and are/will do anything that's necessary for our Early Access and -- eventually -- the full launch to be a success.

If you have any questions, suggestions on bugs, please do report. :)

Currently in early access you can advance your character, play multiplayer game in sessions with all 8 classes and try to survive for 1h in random encounters.”

Will the game be priced differently during and after Early Access?

“We are offering some great discounts and bundles during Early Access, so by purchasing early you're definitely getting a great deal. The price will be higher at launch.”

How are you planning on involving the Community in your development process?

“We're looking for YOU to provide as much feedback and bug reports as you can! We want The Red Solstice to be one of the best co-op/multiplayer games on Steam, and we'll need YOUR help to get it there. Feel free to ask us any questions on the Steam forums, our Facebook page, Twitter or wherever else you want. We'll also schedule frequent play sessions and special events with the development team, so keep your eye out!”

Version 2.60

Finally we can say that we are getting happy about how the game is looking from a technical standpoint. Deeply buried engine problems that were driving us mad by causing random crashes have been mostly identified and patched up, parts of the network engine have been optimized and are behaving more reliably, and optimizations of the resource loader have given us much more satisfying loading times. Of course there is much left to be fixed and tweaked in the engine, but current situation has allowed us to finally step out of the "this must be fixed NOW" mode and divide our manpower between technical fixes and content generation.

As a result, with this patch we bring you 2 new missions, one legendary (for experienced players only) and one secondary. We are also introducing one bio signature mission featuring a new boss.

Weapons have been tweaked a bit. Arclite damage cap has been removed (should provide a nice buff to hellfire class), and pistol has been given an ammo costly but high damage burst mode.

Among monsters, holers will be seeing greatest changes with this update. They will burrow now, and while they are burrowed will move underground, ignoring all obstacles, damaging everything above them. Everything includes turrets and other items. With these holer changes, different tactics will have to be used to eliminate them efficiently, increasing the importance of the seismic resonator items.

Follower AI has been greatly changed. They will no longer linearly follow a player they have been assigned to, but will have their own move patterns, avoiding monsters and explosives, while still keeping in a certain radius around their assigned player. They can still be assigned, unassigned and ordered to hold position, but will also automatically follow a player that comes near them when they are discovered. This new AI system will require further tweaks, but we are very happy about how this change has impacted gameplay so far.

Ironward team wishes you happy hunting!

Full changelog:

- added 2 new missions(1 legendary and 1 secondary)
- added 1 more bio-signature mission with new boss
- extended duration for hatchling missoin by 2 minutes

b) moving towards mid section of closest teammembers
- if there is boss near, they will run in opposite direction of the boss

The Red Solstice gets free Horrors of Mars update. Get it at 40% discount for a limited time!

8-Player Tactical Co-Op Survival Game Is 40% Off on Steam Today

Iron Ward has launched a major, free update for The Red Solstice, its 8-player, tactical co-op survival game. The Horrors of Mars update adds two deadly new bosses that will greatly impact gameplay, requiring extensive teamwork to defeat. The update also includes extensive gameplay improvements, including completely overhauled tutorials and other features that help make the learning experience a bit easier on new players, as well as significant network optimization, new Steam achievements and a range of gameplay fixes and balancing.

Take a look at the two new bosses in this new trailer for the Horrors of Mars update here.

List of notable changes done in the last few weeks and included in this patch:

Gameplay changing boss fights:
Ker, the sandworm:
- Surprises prey with subterranean attacks
- Protective carapace provides heavy armor
- Gangly, spiny legs strike swiftly
- Mandibles and teeth will tear soldiers apart

- Incredibly fast and agile
- Terrifying roar strikes fear into all but the bravest
- Isolates prey, dragging them into darkness
- May be showing signs of maternal behavior

Learning curve adjustments:
- Expanded “prologue” (tutorial mission) to make some game systems more clear to beginners.
- Implemented new readable instruction type tutorial that can be accessed from the game lobby and from the game itself (will pause the game if playing solo). Click the question mark icon right of the minimap to access new tutorial.

Network optimizations:
1) movement
- 2 separate systems to fight both desynchronisation and low responsiveness in high latency environments.
- Forced delay: user’s avatar will respond locally with a delay to allow the package to reach other players, so that the action can be performed simultaneously
- Dead reckoning: if packet travel time is so large that introducing a delay would negatively impact user experience, movement will be executed locally before other players get the information, but they will calculate that player’s real position using his speed, locally reported position and network latency

2) Attack
- In higher network latency environments, long packet travel times caused issues with some shots not doing damage.
- Introduced desynchronisation fighting algorithms based on network latency prediction and forced action delay

3) Skills
- Introduced desynchronisation fighting algorithms based same principles as above

4) Unconnected ping
- Users will now be able to see hosts ping in the lobby without having to connect to him

5) Network traffic reduction
- Various packets have been reduced in size and some network algorithms have been optimized, resulting in considerably less network traffic generated

Reworked controls system:
- All actions (except for inventory hotkeys) were bindable to one key only.
- New system allows for one action to be bound to a combination of up to three keys

Technical improvements:
- Changed texture compression method, leading to considerably faster loading times.
- Optimized graphical engine, allowing for additional 10-ish fps
- Fixed number of engine issues that were compromising game stability
- Selecting resolution greater then desktop resolution will reset the in game setting to match the desktop resolution.

Other improvements:
- Barrels, stroll substance and some other destroyable items will now have health bar shown
- New menu music

Early Access Review
When you're first starting out, the game is really hard even on the easiest difficulty setting. I HIGHLY recommend reading the player guides if you want to get any good at this game. Once you know what you're doing and have a coordinated team, beating the game on easy and normal difficulty is a piece of cake. In that case, you might want to try hard or nightmare difficulty, both of which are extremely brtual.

The community here is quite small. The veterans are quite welcoming if you're willing to learn, follow directions and get teamspeak. You don't have to talk on TS if you don't want to. As long as you can hear everyone else, then it's okay.

Early Access Review
I can not recommend this game right now.

This game is great, you start out with little to no idea what to do, you die, sometimes you might get saved, sometimes you don't.
You earn EXP and it means something, from new weapons and classes to small increases to damage and movement speed.
You have a lot of fun dying and dying again.

The downfall is for any of this to take place you need to have other people online to play with, And even right after patch, you will be lucky to get 6/8 lobby filled. As it stands I can not recommend picking this game up unless it is on sale or it is fully released, they complete single player, or they add NPC's that do more than follow you, because no one is playing it, and I know this review is kinda self defeating, but it is the truth.

If you enjoyed playing the RPG custom games in StarCraft, you will love this game. It builds upon that concept, bringing players into a new world with an interesting progression system and customizable options. It is still a work in progress and I look forward to watching it continue to expand and get even better.

Do you remember this map in Warcraft 3? Where you and other people play as a marine trying to survive in a city? Yeah, this game is basicly it on a new level. The game is good and decently optimized.
But devs need to solve one thing ASAP: they need to figure out how to hold players in this game.
Hear me out here. With this game in it current state devs will never be able to hold an average player for more than a 5-10 hours. And the rotation of players will be too small for this game to be populated. Devs need to make something for players to come back for, make game as random as possible.
Best solution i see is making more random events. Making more rewards. Making more progression trackers. Making map being random or semi-random on each new play. Add more winning conditions, so players losing every game will not feel themselves drained and abandoned.
I played 10 hours and i don't think there is something to come back for. Maybe once a week with a friend. Maybe. But thats not enough. How will they keep money flowing? I don not know. I just hope they will figure this out. Microtransactions on customization is something i could easily accept.

squad based, skill based anti zombie/bio horror diabloesk shooter. every class brings needed skills to the table, every class is unique. just remember, never wander off by yourself. just like a horror movie, you would be a bit character who gets to scream and die.

i still like the game but with current setup, if you screw up... even just a little, yer dead. the older version used to have some leeway as to how you played. but i still like it.

Really good RTS style tactical coop game. Play with up to 7 friends and go against hordes of Mars' horrifying inhabitants. i must admit the game is pretty challenging but not too much of a learning curve if you watch some gameplay vids and or play with friends.
Overall i recommend this game even in its early access state.

Early Access Review
The game is very tactical, you need to work as a team (this however means it has the problem of random groups which could lead to nothing), it takes alot of planning and failing a few times over to learn what comes when, and what you need to be ready for.

This game is good if you like playing with many others and play a role in it all.
This game is bad if you like playing on your own and don't keep a tactical eye on your surroundings.

Incomplete game DEMO, nearly an hour of game play, designed to trick people into paying, hoping for complete game.
- Development site forum identifies as 'Alpha' state, though advertised as 'Beta' and 'Early Release'....Alpha state is more accurate.
- Asking 'uncomfortable' questions in forum results in bann.
- Development team appears to consist of Russian Hackers: Buyer Beware!
