Sept 26th - Patch Notes - Alpha 1.5 (Hordes | Free Placed Fortifications | Devlog++)

Hello all,

We’ve released the 1.5 patch to our stable branch on Steam. You can find our patch notes below. There’s a lot of testing and breaking to do so go at it! Please do your best to check against the list of changes and report bugs using the in game bug report system.

Survive the Nights - Alpha Devlog (1.5 Update Showcase)

Alpha v1.5 Showcase Trailer

Free Placed Fortifications

Along with hordes, free placed fortifications will really change the gameplay. Zombies actively hunting the player each night will create reason to fortify a structure and free placed fortifications will greatly increase your chances of surviving the horde. The mechanics behind them are rather challenging and interesting. Zombies have to be aware of placed fortifications, they have to attack fortifications, they have to avoid them when possible, receive damage from them and they have to stop attacking them when you're no longer behind them. The mechanics are coming along quite nicely with the visual aspects (something we'll showcase next week). You should be able to place them in the upcoming experimental patch, we'd like to get that to you early next week. Below is a video showcasing some of the AI logic, registering and attacking a placed fortification also being damage by the barricade. They also stop attacking and attack the player when he moves to the opposite side of the barricade. Below that you'll see a gif showcasing the logic rotating toward a fortification.

New Fortifications

The initial 1.5 build will feature 4 types of freeplaced fortifications. Concepted by our moderator and concept designer Num47 and created by Andre the fortifications can be placed anywhere in the world and strengthened/repaired. They can be completely destroyed so be sure to keep on top of repairs and replacements if you want to keep that added level of security to your structure. Along with these additions you'll find you're no longer safe on top of vehicles as zeds will now attack and damage them to the point of explosion, killing you along with themselves.

Quick Concepts from Num47

Implemented in game. You can see the 4 variants here.

Fortification Improvements

The current fortification method when it comes to covering windows with planks/boards only allows for a hammer and nail setup. This simply wasn't fast enough in most cases so we've expanding tools a bit. You can now use a screw driver and drill to apply fortifications. The screwdriver is faster than the hammer and the drill is obviously faster than the driver. You will need screws for both drill and driver, nails still being required to apply fortifications with a hammer.

Horde UI Concept and Preview

Horde mode will feature quite a few new mechanics. One of which will be a UI to keep track of a few things including how many 'horde nights' you've survived, how many zombies you've killed, when the horde starts and stops along with the direction the horde is approaching from. These features and this UI is all in its infancy, We'll have far more information in coming devblogs along with experimental patches so you can start testing these new features.

The player will receive in game notifications for both hordes approaching and XP/Level notifications. You'll have a limited time to flee before the horde arrives, you'll be notified when you're leaving the hordes reach. Players that choose to flee will not receive the larger XP boost from killing the horde.

We've made quite a few adjustments based of community feedback with our experimental patches, one of the suggestions that made it in was a horde difficulty reset. Upon death the player is able to reset the horde difficulty with the slider below.

New Animations

You'll likely be seeing far more zombies in the coming updates. We've improved and will continue to improve zombie characters and animations. In the 1.5 builds you'll see the start to some zombie animation tweaks. Creepier leg dragging and more fluid movement helps to add to the horde vibe. We've also spent some and started tweaking weapon animations.

Merch Shop!

While we're currently unable to sell merch in house (which is what we would ideally love to do one day), we've opted into a 3rd party seller, Teespring. They will provide those that have requested it the ability to pick up some cool merch and help out the team.
