About

Planet Eldra

Read full description

The distant Planet Eldra. This world was once covered in endless grasslands. Herds of great beasts treading the earth, shadows of wings streaking the sky, bioluminescent trails glowing in the darkness โ€” countless lives intertwined, and the planet breathed as one living organism. But the balance collapsed, and the land fell silent. You are the one who will breathe life back into this world. Release herbivores, introduce predators, cultivate decomposers. Eat, be eaten, die, return to soil, and sprout anew โ€” restore that cycle to this planet once more. โ€”โ€”โ€”โ€”โ€”โ€”โ€”โ€”โ€”โ€”โ€”โ€”โ€”โ€”โ€”โ€”โ€”โ€” Once placed, the creatures begin to act on their own will. They graze, hunt, breed, and eventually return to the earth. Even without your intervention, the ecosystem shifts moment by moment. But life is never so simple as to "work itself out." Too many herbivores, and the grasslands vanish. Without predators, reproduction spirals out of control. Without decomposers, the land rots from within. Vegetation and soil, weather and plague, birth and death โ€” amid this web of interconnections, what you seek is "stability" โ€” a fragile miracle. โ— Unique creatures with autonomous AI behavior โ— Real-time simulation linking vegetation, soil, and weather โ— Gene tuning to adjust lifespan, fertility, and resistance โ— Diverse stages unlocked progressively, plus Hard Mode โ— Concept art and detailed creature encyclopedia There is no single right answer. Build your own ecosystem on Eldra.

About

Abyss Expedition

Features
Read full description

Abyss Expedition is a strategy roguelike RPG about drawing equipment, arranging your bag and fusing gear. Combine equipment effects, companions and skills into your own build to challenge dungeon bosses. โ–  What will you pull? Draw equipment from the loot board, one item at a time. Land the rare piece you've been hoping for and put it to work in your next battle. Got a good item? Check what's still on the board before you leave. โ–  Keep drawing, finish the board, or move on? The item you want is still there: try another draw. Only a few slots remain: draw them all and empty the board. Nothing left catches your eye: switch to a fresh board. It's your call. Look at the remaining items and what you can afford to spend. Drawing every slot gives you supplies and a choice of upgrade for this expedition. Switching boards has in-game conditions and costs. A new board isn't always better. โ–  Put your gear to work Equip your finds and fight the dungeon's monsters. Match equipment effects, arrange your bag, and bring companions along to take on the kings of the Abyss. Stay for one more draw, or see what's on the next board? Free to download. Contains ads and optional in-app purchases, including randomized items. Account linking, cloud saves and online features require an internet connection. Support: tnwlstkfkd1025@gmail.com

Verdict

The call

The clearest difference is ads: Planet Eldra at none against Abyss Expedition's shown. Abyss Expedition's advantage is update cadence (every 2 days vs weekly). On price, in-app purchases, device support and iOS requirement there is nothing between them.
