Alien Core [v0.0.3] [Core-Ruption Studios]

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?

Changelog:

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)
