Space Bob vs. The Replicons

Space Bob vs. The Replicons is a procedurally generated gravity simulator in which Bob ventures to hostile planets to recover loot and resources, then hauls them back into space to salvage into materials for crafting and survival. As replicating robot bugs invade, Bob is the only one who can try to stop them. The game also involves time travel and a mysterious, powerful being behind its multiverse and time-travel events.

Explore and grapple

You shoot bugs and explore planets, using a multi-functional grappling gun that can attach almost anything to anything. You can grapple loot to Bob, other loot, his lander, ceilings, enemies or bombs; you can also attach enemies to walls or to each other. These combinations let you find different ways to handle situations as they arise.

Each game generates a new planetary system. Its planets are remixed with different resources and loot, so each run offers a different open world. Objects, planets and even blades of grass are modeled with polygons, allowing you to zoom from a view of an entire planet down to individual blades of grass without visible pixelation.

Game modes

Both open-world modes combine roguelike and survival elements, but the game describes itself as neither one nor the other.

Invasion Mode

Invasion Mode is the original, story-driven mode, with permadeath and other roguelite elements. A game typically lasts one to three hours, and completing the story takes multiple games. The mode is designed for replay, and Bob faces frequent threats. You can raise the difficulty to increase the score multiplier and compete for leaderboard positions.

Survival Mode

Survival Mode is the more relaxed of the two modes, focused on lasting as long as possible. The Replicons invade more slowly and in smaller numbers, loot respawns over time, and you can pursue a single overall goal in a sandbox-style world. Permadeath still applies, but a teleporter can automatically save Bob from death if you have enough resources to power it. Runs can last tens of hours, and the mode is aimed at exploring, experimenting and playing without much pressure from objectives or time limits. Higher difficulty settings remain challenging.

Leaderboards

Each mode has two score-based leaderboards: one tracks the highest score in a single game, and the other the highest combined score across consecutive games without dying. The game also has two speedrunning leaderboards: one for a shorter run and another for completing the entire game.
