Alien Core is a 2D Stealth-Focused game with Impregnation and (not currently but planned) corruption as it's main focus. The game will work similarly to a metroidvania, where you go from zone to zone, unlocking areas as you progress. Story: The player character was just taking a break under a big tree when a bright light spread across the sky. When they come to, they find that they are the only one left with their mind intact, everything else became brainless drones that only look to procreate. Will the MC be able to figure out what happened? Or will they be corrupted along the way?​

V0.0.4c - Fixed an issue where the camera got stuck after running out of Endurance V0.0.4b - Fixed major bug that caused the game to soft-lock when traveling between areas V0.0.4 Entirely Re-written Pregnancy Code: This does not effect gameplay directly but it should make any future adjustments to pregnancy far easier to implement (This was kind of necessary for Oviposition). Oviposition!: Two new types of pregnancy has been added, the Bee infests you with maggots, and the Hugger implants you with Eggs (The Egg visuals could be better I admit, have ideas on how to make them look better). For now it is only vaginally, but I will certainly look to the possibility of adding Oral/Anal options in the future. New Enemy Horse!: They run fast if they spot you so make sure you are near cover. Can be found in the last 2 areas. One New Area + 2 Slightly expanded areas: The Alien spaceship where you find the key has gained a small second floor, the previous final zone has been extended with horses, and a new final area that makes use of the new climbing mechanics has been added. Climbing!: The player can go up ladders by holding W or Up arrow. NOTE: since you are likely to skip the tutorial, to climb back down a ladder you need to hold down and press JUMP . This is so the player can still crouch near ladders. Gallery!: A gallery is available on the main menu, I will likely add a unlock condition in the future but for now it will always be accessible. Updated UI during gameplay: I move things around and updated some visuals so everything should be much clearer and nothing should cover anything anymore. BUG FIXES/CHANGES: - Key will be saved upon rest: This was a bit complicated as it needed to be future-proof for all items, I hopefully have achieved that. - Fixed wall in the spaceship - Hopefully fixed a ton of issues with pregnancy, though since I just made the new system there might still be bugs - A lot more stats should be properly saved like last partner and birth count - Probably a lot more but I did a bad time tracking this time round and don't want to waste time recalling all the stuff, let me know current bugs! V0.0.3 Two New Enemies added! There is the Hugger which can hide in the grass making it easy to be surprised. - The other enemy is the Giant Bee, who flies above the player and swoops down slowly making them potentially easy to dodge on their own but tough in a group. One New Area: The entrance is next to the house with the bed and will introduce the concept of different paths to the game. Both the Bee and the Hugger can be found within this new area and while this may be the only place for them now they will be used in more spots as more areas get added. The key has been moved here and so it is required to visit in order to get to the ending. There is a door that requires a keycard, this currently has no way in. Impregnation on sex! If you are ovulating you can now get pregnant right after sex. Twins/Triplets have been added! This includes larger pregnancy stages for when it happens. Pregnancy Options! Adjust the Pregnancy Chance along with the chance for Twins and Triplets within the option menu. You can also switch back to the delayed pregnancy that the game had before. More Thoughts! The text box now has unique dialogue for each enemy upon getting attacked. Limited Corruption has been added! Repeated sex acts will gradually affect characters mental state, this is reflected in the portrait as well as the thoughts they have when having sex with the various enemies. This does not affect generic actions like resting for the time being but will in the future. Ability to Zoom in! You can now cycle through three stages of zoom using the X key, a sign was added in the tutorial as well to explain this. Mini-map item was added! Added where the key used to be, picking this item up will give you a mini-map in the top right corner of the screen which will show how each area is connected (not much more for now) There should also be some bugs that are now fixed but I would not be surprised if new ones show up. Also Android should work on all Androids now hopefully (I can't really test it myself) V0.0.2 New Character Lily! Comes with unique Dialogue and Voice - Visual overhaul of player characters and enemies, with new models for the player characters and all sprites have double the resolution. I really liked how it turned out so I hope everyone else does too. - Android release! This took some learning but it was not as bad as I thought to add touch controls. (Double-Tap arrows to sprint, double tap interact to bring up status, triple tap interact to adjust character portrait) - You can now crouch with the down arrow, silly oversight on my part... - Added audio to birth scene - Pregnancy now is reflected in sprite sex animations (Not the portraits yet, thought about it late and don't want to delay this any longer) - Extended all sex animations, with varied animations throughout - Going back to previous areas now spawns you at the exit instead of back at the beginning of the level. - Bed now restores Endurance and has dialogue associated with it - Added small third area (Was not the focus, want to add new enemies before creating too much extra areas) - Key's are now removed upon use and you can no longer grab multiple before it disappears - Status Screen now updates to the current character portrait - Adjusted Walk and Idle animations to fit better with the new models (less exaggerated) - And a bunch of bug fixes (though I doubt I got them all) v0.0.1b - Fixed the game always crashing when having s** after giving birth - Fixed moving areas after giving birth resulting in another pregnancy - Fixed portrait not always updating after giving birth v0.0.1 Initial Release

kinda skeptical at first because of the ai cg portrait, but it is good enough gameplay wise, i think it's hard since you have no means of attacking at all overall, quite nice, x-ray scenes could use more polishing though and if you have the money, consider hiring an artist for the portraits or learn to draw yourself anyways, good luck on this game

simple gameplay is nice artwork is good neeed a lot more content the dog sex can be kept to a minimum not really animated during the sex scenes has a lot of potential though I hope a lot of improvements are coming in the next releases

Already a great game as of v0.0.2. The jump from 0.0.1 was also very significant with new pregnancy mechanics and a whole 2nd character being introduced in a single update. Pros: + Stealth gameplay is fun and well executed. + Good difficulty (hard but lots of checkpoints) + Very hot poses / sex CGs (don't look AI). + Multiple character variations. + Pregnancy variations. + Good ambience and level design, the game has a soul and an art style. Cons: - Animation is passable, but not to the level of the portraits. Two stood up to me as very ugly: the walking / jumping animation, and the womb view (although X-ray is a good idea the sprite itself looks quite bad). - A few bugs here and there.

Love the non fighting / sneaking experience. The mechanics work without flaws (that i manged to detect) Sure it could use work but its a very early stage. It's not easy but it is not meant to be easy. its just hard enough to get into real trouble. I would like to see a way to replenish your endurance But i am glad it is not to easy also the save doesnt seem to work well after dying you seem to not revert back to your save. please continue this effort. Don't get discouraged by the nay sayers

It's very rough around the edges. But it's a test build 0.0.1 so it'll probably change in the future. What I would reccomend is to focus on better models and animations, especially during the lewd scenes (this is a porn game after all). Here's a short list of things this game needs: -more lewd scenes with same enemies, and more enemy types -longer scenes, -better models (more details like in other dot.pixel games) these ones won't do, especially the female model, -better enemy behavior (I got stuck at two drukards because the second one didn't want to turn around). Extra star for pregnancy as this is always an upvote for me.

Trying to help balance out that 2 star since that will inevitably kill this game before it has a chance to actually get rolling. The in game sprites need work as does the sound and such, but for a 0.0.1 this seems like it has potential. as stated before, the sprites need some polish as does the scene length sound and variety but this really should shape up to be decent.

This game needs some work, but it has my interest for such an early release. The animations need to be longer for starters and could use some polish, along with some variety, also some bugs need to be worked out, but this is clearly a proof of concept.
