    More Info on Weapons!

    For those that are interested in what sort of weaponry will be at your disposal during your fight through the hells, this is the post for you! We wont be talking about your suit or your gear in this post (stay tuned for more info on these) , just weapons. In Sempra Infernalis, you don't start with a wide array of ordinance at your disposal, but as you progress through the game and earn essence (obtained from your fallen foes) you will be able to unlock new more powerful weaponry to improve your demon slaying ability. Some weapons can be purchased with your collected essence, some can be unlocked through playing the game and others, must be built! Below you can see the the starting pistol, and a more powerful item which is currently locked. Playing the game and killing hell spawn will unlock this weapon, amongst others. {STEAM_CLAN_IMAGE}/44946766/1a372e0991232caca99f60cb05bf9684a93c6066.png Below you can see two shotguns, one is available immediately, provided if you have enough essence to purchase it. The other, like the pistol above needs to be unlocked. {STEAM_CLAN_IMAGE}/44946766/b4d6c2227bb65edb4236ccc236fcd508194ac53f.png As you play, more and more items will be come available to purchase, upgrade and equip. Almost every item in Sempra Infernalis can be upgraded. The only exception is legendary weapons. Legendary Weapons must be built. In order to build them you must find their required parts. Each legendary weapon is made up of 6 parts, those parts are located around the map, powerful enemies or Mini Bosses may also drop parts as well. Once you have all 6 parts of the weapon, you are able to equip it straight away. Be warned, though. Legendary Weapons are over powered and have additional status effects such as pinning enemies to the terrain behind, setting them on fire or even just blowing them to bits completely.

    Exciting New Content Being Implimented

    Last week we had to announce a delay to the launch of Sempra Infernalis. But, we are pleased to report that our hardware issues are completely resolved and development continues in earnest. From this day on, in addition to general updates, we will be talking more about specific features and game content in more detail. Today, the Achievement system! Constant Progression In Sempra Infernalis Every time you play, you will achieve something. Be it a minor a major milestone. But how does this work in practice? Every felled enemy drops Essence. Easier enemies drop less whereas harder foe's drop more, further the value of the essence dropped increases with enemy difficulty. This must be collected by the player by simply passing through its space (running over it). When you die, and yes you will die, lots... all of your progress from that run is lost, except for essence. This is taken back to your sanctuary and can be used to buy new weapons and items, upgrade existing pieces or to increase your speed, health etc. Essence has an additional function though, it acts a proxy for XP. The more you play, the more essence you will collect. That running total of essence collected progresses you through a sliding scale of achievements. So even when you have died for the hundredth time, you may still be able to unlock items to increase your chances of success on the next run. You might unlock a essence dump, you might unlock a weapon part (keep an eye out for future announcements that will detail how you can build crazy powerful weapons), a permanent boost to damage or health or your speed. You might also unlock new and unique items not available anywhere else in the game. We hope that this system is familiar to players (we certainly didn't invent it!) and will keep players having fun for longer. Because that's the focus of this game. To have fun. We look forward to you being able to experience this in the near future. If you want more information or want to share your thoughts on t...

    Release Date Update

    Sempra Infernalis was due to release on 16th July 2024. We are pushing that back for a few reasons which we have detailed below. Before we get into the WHY, we are 110% committed to releasing Sempra Infernalis in the very near future. However we want to ensure that when we do release, you the player has a high quality and enjoyable experience from the outset. Now onto the WHY… We have had some hardware related issues… When we planned the development of Sempra Infernalis, we did not account for a major hardware interruption. To say we have been a bit unlucky here is an understatement. However in short, the machines we use to develop Sempra Infernalis need to be replaced. Porting the vast amounts of information over to the new hardware is taking time that we would like to be polishing game mechanics. We have mostly completed this task and will soon be back to finalizing the release version of Sempra Infernalis. Some key features are not working as intended… We need more time to address platform optimization to ensure Sempra Infernalis can be enjoyed on the vast majority of PC specifications. In addition to this, some gameplay features are simply taking longer to fine tune and balance than we predicted. We want to add more content… Additional enemies and level expansions are currently underway, we had these pinned for free post release patching but due to some projects completing quicker than expected, we have the option to increase the games scope in the early access release version, this means there will be more room for exiting new weapons, enemies, mechanics and environments in the future. For those that are following development and are adding Sempra Infernalis to your wishlist, we REALLY appreciate the support. Rest assure Sempra Infernalis will release soon. We can’t wait for you to play and let us know what you think. If you have any queries or want to know specific information about the development of the game, head over to THE DISCORD. We would love to chat w...

    DevLog - 31st May 2024

    Hello, Oliver here! We want to include our players as much as possible in the development of Sempra Infernalis (SI) so we will be posting weekly DevLogs to keep you updated with what’s happening behind the scenes and explaining more about the game’s finer details. In SI, it is essential for you to upgrade and fine tune your character stats and loadout. To facilitate this, we need a robust User Interface (UI) that gives the players as much control over their character as possible whilst also keeping the User Experience (UX) as simple and as intuitive as possible. We have expanded customisation options for almost every upgradable element in the current early access version. For example, grenades are great way of clearing out a bunch of enemies quickly. You can now customise a grenade’s area of effect, its total damage value and how many you can take with you into hell. We hope this level of customisation gives players a real sense of control over how they progress within the game. Of course, this is just ONE of many items that players will be able to unlock and upgrade at release. We have a whole load of really cool and interesting ideas to expand the players inventory options as we progress through early access. We can’t wait for you to dive in and explore this aspect of the game. We will be posting some screenshots on the main page in the next few weeks. If there are any aspects of the game or its development you would like to know more about, drop in a comment and we can address these as a priority. Our Discord should go live over the weekend which we will make a separate post about, we hope to catch up with you there. Until next week’s update… have a great week ahead! Oliver
