Neon Abyss 2 is a side-scrolling shooter with pixel art and bright neon colors, set in a mythical underworld the developers call the Abyss. You run through rooms, blast enemies, fight bosses and collect items that change how your character plays. Die, and you start again with a new layout.
The big change from the first game is the weapon system. Instead of mostly shooting, you can now pick a fighting style. You might swing a saber or a bat up close, send plant-based attacks at enemies, or command dragon-like creatures to fight for you.
Item synergies (items that combine into stronger effects) are back as well. There is no cap on how many you can carry, so a lucky run can snowball into something absurd. Veewo says the sequel adds more than 600 new items, which is why no two runs are likely to look the same.
Items are only part of it. The sequel also throws new enemies, bosses and gods at you, along with hidden secrets and reworked loot, and levels are still put together at random. Even the unfinished test version beat the first game for sheer size, with more stages, foes, bosses and playable characters, and it brought back every enemy and boss from the original as well.
