Evaluation

Gunbot Diplomacy: Blast Off is a free-to-play prologue teaser for the main game, Gunbot Diplomacy. The store description is explicit: it is a "prologue teaser build" offering a limited slice of content — two gunbots, eight weapons, 50 modules, and the first ten maps. Its purpose was always to serve as a preview for the full game. The full game, Gunbot Diplomacy, launched on May 13, 2025, as announced in a news post that same day. All the patches observed in the news feed — including pre-launch balance work in early May 2025 and subsequent feature patches through December 2025 — appear to be updates to the full game rather than expansions of the prologue itself. The prologue was released on April 25, 2025, and shipped as a deliberately scoped, finished teaser product. No content has been announced specifically for Blast Off beyond what it launched with, and the developer's development focus has clearly shifted to the full Gunbot Diplomacy release. The prologue functions as a standalone, complete sampler — it was never designed to be expanded, and there is no evidence of planned additional content for it specifically.

About this game

Gunbot Diplomacy: Blast Off is a prologue teaser to Gunbot Diplomacy. You'll have the opportunity to experiment with multiple Bot builds, providing plenty of replayability and a few hours of potential gameplay.

Content available in Blast Off: Two gunbots, eight starting Weapons with plenty of augments and ammo to customize them, 50 Modules + the first ten maps of the game on the base difficulty, featuring 20 unique enemies.

Assemble the perfect arsenal of weapons, from nuclear footballs to fire extinguishers that spray electrified flames. Rewire your Gunbot - frame and (artificial) brain - whether it's for speed, durability, or straight up firepower. Welcome to the wasteland; now pick your flavor of carnage!

Features:

-Infinite replayability! No two bots are the same, so no two runs are the same!

-Mix and match from over 20 base weapons and customize them to suit your build on a unique hexagonal upgrade grid

-Choose from more than 80 build-defining modules - it's not like messing with Gunbot AI lead to the downfall of all human civilization or anything!

-Fast-paced gameplay: let your weapons do the talking and splatter your enemies across the desert, while you dodge out of harm's way!

-10 base Gunbots to choose from, from the gallant LanceBot to the Freezer, the best armed fridge the world has ever seen!

-Discover hidden combinations for special evolved weapons to kick your build into overdrive!

-Fun and varied enemies: oozified office workers still on their 9-to-5 grind, brawl boys who just want to fight everything that moves, skittering spine-slinging crab/cactus hybrids, and so much more!

-Special Hazard and Boss levels to test your build - and skills - in unique conditions!

-Let your gunbot's automated targeting systems handle the firing - or select which weapons you want to manually aim for optimal control!
