This week we’re introducing Horde Mode, our first variable emergent event in Icarus. Randomly scattered throughout prospects and outposts, will be Enzyme Geysers which reap valuable rewards but are beacons for waves of dangerous foe hellbent on destroying them. These will also be available in your new, 64sqkm Olympus Outpost. We’ve also completed a recent engine upgrade and worked with NVIDIA to add more capability to NVIDIA Reflex, along with backtracking on a change we planned to implement this week, due to some unforeseen circumstances. Have a read and ready up for the Horde!

Horde Mode

Horde Mode is here, and we couldn’t be more excited to introduce our first variable emergent event to Icarus, complete with high levels of chaos, danger and bountiful rewards.

Enzyme Geysers

Enzyme Geysers are natural structures that are scattered throughout Icarus (on Olympus, Styx, Outposts and future biomes). Players can craft and deploy a ‘Vapor Condenser' on top of the Enzyme Geyser in order to activate the horde mode. The Vapor Condenser can be crafted in the Fabricator, so will require you to be high-level.



Defeat the Hordes

While the device is active, waves of aggressive creatures will spawn and charge the Vapor Condenser, with the intent to destroy it. If they happen to spot any players, they may choose to attack them instead. The number of players near the Vapor Condenser will also increase the number of creatures spawned to help the event scale with multiple players.

It is the players objective to defend the Vapor Condenser by any means necessary as they deal with 3 waves of aggressive creatures (which vary in type and increase in difficulty). Each time the player defeats all 3 waves the device “levels up” and upon next activation the level of the creatures spawned is increased significantly, making each play through more difficult to complete.



Reap the Rewards

Upon completion, Exotics will be deposited into the Vapor Condenser machine as a reward. This whole event can be repeated an infinite number of times, but the Exotics reward cap is limited, currently at 3. After that, the rewards will become inert and instead of Exotics being rewarded, Condensed Enzymes will be rewarded instead.

Condensed Enzymes are a new resource to Icarus and are starting their journey as an ingredient for crafting Statues, which can be used as trophies in your base to show off your horde completionist skills. In the future, Condensed Enzymes may expand into various other special recipes.

For the moment, completion of this event on an Outpost will only reward Condensed Enzymes, as Exotics cannot be taken back to the HAB with you from an Outpost and would serve no purpose as a reward.

In addition to item rewards we also reward a nice chunk of XP (around 2500) which also scales with the number of completions.

NVIDIA Reflex + Engine Upgrade

NVIDIA Reflex low latency technology is now available in Icarus, providing the best responsiveness available to date. This new feature is one of many NVIDIA backed technical improvements we’ll be bringing to Icarus in the future as part of our partnership with them, and will available with your most recent NVIDIA drivers update.

We have also recently completed a UE4 engine upgrade from 4.26 to 4.27, which will minor in it’s broad impact, is important for us keeping up-to-date with the latest technology and allowing us to stay cutting edge when it comes to Icarus’s development. Unfortunately it does mean a bigger download this week as its quite a big upgrade, but the impacts you will see with this upgrade include better stability, multiple engine Nav Mesh fixes, better frame rates and overall performance improvements.

Remove from Prospect Button is here a bit longer

Last week, we mentioned our intent to remove the ‘Remove from Prospect’ button from the in-game menu, as it’s original intention was no longer needed.

In rather ironic timing, we experienced a series of outages over the following weekend, which we apologize for and thank you for your patience while dealing with them.

As a result, we have reneged on our plan to remove the button while we test out the adjustments we’ve made to our servers and to protect players characters a while longer as we confirm these improvements will not put your hard work at risk.

COMING SOON | Dedicated Servers & Decentralized Characters

A major change in future is going to be doing more to provide tools for our community to enjoy the game. Providing Olympus as a full outpost map, customization for outposts, and indeed this update with Horde Mode - is about us working to expand on the concept of what ICARUS is as a game, and the communities role in shaping what it becomes.

As part of this we will be releasing Dedicated Servers in the future and providing them is now one of the highest priorities on the team. This will serve many purposes, particularly in helping ensure great performance for larger teams playing ICARUS together - dedicating the heavy lifting for hosting to a dedicated application.

Additionally, we will be continuing work to decentralize storage of character and prospect data, which will open up more possibilities for modding and user generated content - as well as forming your own communities around dedicated servers. We will continue to release more details in future updates, and extensive testing will be occurring with the community as is custom with any of our large updates.

Many of the changes we make for this won't only benefit those using multiplayer, as their functionality will directly feed into those playing in the offline mode of the game. We also acknowledge the difficulty in maintaining balance for solo and multiplayer, and will continue to work towards better balance for both play situations.

COMING SOON | Outposts: Respawn Location

Some have noted, both on the forums, discord, and reddit, how frustrating it is to try and enjoy the Olympus Outpost map when you spawn in at the drop location each time. We will be addressing this in a future update as a priority.



If you were also wondering why this patch is a day early, it’s because tomorrow is Matariki, New Zealand’s national holiday to celebrate the Maori New Year.

Changelog v1.2.4.97945

Note: The changelog now includes all changes to the project, not just ones to the product.

Horde Mode

• Add biome-specific horde waves (not yet hooked up into level)
• Fixed up Horde DT row handles on BP actors to represent what biome theyre in and added function for updating this
• Adding New Datatables and Enteries for new Horde System
• Adding Component and logic for new Horde System
• Hooking up Analyzer Transmitter to use new Horde System
• Adding First Pass of Horde Mode to Engine
• Adding New In World UI for horde mode which reflects the machines statem, number of waves, progress in current wave, etc
• Adding Inventory for Horde Rewards to the Analyzer Transmitter
• Setup Basic Horde Mode Datatables so new Hordes can be created and Triggered
• Updated Both Inworld UI and Interacted with UI for Vapour Condensor so it works with the Current state of the Horde
• Added CompletionsUnitInert and InertReward elements to the Horde Datastructure
• Hookedup the multipler so each Horde which is triggered is scaled by the number of completions present on the Enzyme Geyser
• Adding new Experience Event For Horde Completion
• Horde Mode is now completeable multiple times on a single node with the multiplier scaling the difficulty and rewards upon each subsequent use
• Added ability for Horde Spawners to spawn around pre-designated QuestMarker actors placed in the level, instead of using a generic EQS centred around condenser location
• Added prospect difficulty and player count scaling to horde mode spawning
• Fixed issue where horde mode could spawn more AI during a wave than desired, and go over the 100% completion progress limit
• Change item rewards for Horde inert to be a single Enzyme item
• Horde mode in world widget UI pass.
• Change interacts around (Hold F now activates, Press F opens inventory) to prevent accidental wave stopping
• Replaced references to waves in the UI to mention stages as to allow it to make more sence in terms of activating a machine rather than a game mechanic
• Added a 1s delay between simultaneous horde spawns to spread out AI and reduce likelyhood of FPS hitches
• Add new Getter function for spawned creature levels with a larger (0.5x) multiplier to increase the creature levels per horde completion (now 25 -> 38 -> 50 etc)
• Add character growth setups (matching Jaguar) for Cougar and Snow Leopards, so they will now scale with their level
• Fixed spelling on Vapor Condenser itemable
• Tweaked horde waves: Shorter delays for 2nd waves, only 1 additional Bear per player, Polarbears spawn at level 1, more Hyenas at a time, numerous changes to make Scorpion wave more difficult
• Fixed erroneous setup of Jaguar which was getting its health and melee stats from two different sources, doubling its effectiveness
• Multiplied base stats curves of Jaguar (also shared with Snow Leopard and Cougar) by 1.5x after dual stat correction (slight nerf to Jaguar, buff to Cougar and Snow Leopard)
• NPCs no longer leave blocking collision behind temporarily after death, should make large groups of AI more predictable when fighting and will stop them running into invisible barriers
• NPC corpses no longer tick when their ragdoll simulation has full settled; significant performance boost in situations where player is surrounded by many dead NPCs. NPC corpses that come into net relevancy will now use the hosts cached ragdoll pose instead of having the cilent re-simulate their own. This should further reduce cases where dead NPCs fall through the world, especially when returning to carcass from far away
• Dont reward Exotics on Outposts as they cannot be taken back to HAB from an Outpost
