Game River released Mechabellum out of Early Access on 26 September 2024 with Dreamhaven publishing. It is an auto-battler played entirely between rounds: you spend supply on units, place them on a grid, buy tech upgrades and draft reinforcement cards, then watch the battle resolve without touching anything. Around 29 units exist, and almost every one of them is the answer to some other one, so reading your opponent's board matters more than any single strong unit.

Starting Mechabellum can feel overwhelming. This guide tells you exactly what to focus on during your first hours so you don't waste time on things that don't matter yet. For the full progression path, see our walkthrough.

What Kind of Game Is This?

Mechabellum is a strategy game built around Round-based deployment on a grid and Unit tech upgrades. The core loop involves mastering these systems to progress through increasingly challenging content.

What to expect: Time investment in learning mechanics, experimentation, and gradual mastery. The game rewards patience and knowledge.

Choosing Your First Build

Build	Beginner Rating	Why
Chaff swarm	Excellent for beginners	Balanced approach
Anti-air	Excellent for beginners	Balanced approach
Artillery	Excellent for beginners	Balanced approach
Giant	Excellent for beginners	Balanced approach
Air	Excellent for beginners	Balanced approach

Our recommendation: Start with Anti-air. It offers the most forgiving experience while teaching core mechanics.

Avoid Air as your first pick. It requires deep knowledge of game systems to use effectively. Once you're ready, check our classes guide for all options.

First Session Step-by-Step

Step 1: Learn Round-based deployment on a grid

Each round you spend supply on new units and reposition existing ones, then the battle plays out on its own. Units that survive carry over, so a good early placement compounds while a bad one keeps losing the same fight repeatedly.

This is the foundation. Spend your first 15-30 minutes getting comfortable with how Round-based deployment on a grid works before worrying about anything else. Our combat guide breaks this down further.

Step 2: Head to 1v1 Ranked

The main competitive mode and where the counter-reading loop matters most. Practising against the Insane bot first is genuinely more useful than low-rating ladder games, because weak opponents punish none of your mistakes.

Clear the main content here before moving on. Everything teaches fundamentals you'll need later. See our maps guide for all locations.

Step 3: Get Your First Upgrade

Look for Fang: it's the most accessible early upgrade. Cheap ranged light bots that form a wide firing line. The Portable Shield card gives each one a shield absorbing damage equal to its own health, which turns a fragile line into a genuine wall.

Step 4: Understand Unit tech upgrades

Every unit has its own upgrade options bought individually, so an Arclight can take Anti-Air to cover your sky problem or Armor to survive longer against light attackers. Upgrades apply to every copy of that unit you own, which is why concentrating on a few unit types beats spreading thin.

This is the system most new players overlook. Invest time here early. It pays off throughout the entire game.

Step 5: Push to 2v2 Team Battle

Two players share a front against another pair, which changes what units are worth buying. Coordinating so one player covers air while the other covers chaff beats both players building the same board.

Essential Mechanics Explained

Round-based deployment on a grid

Each round you spend supply on new units and reposition existing ones, then the battle plays out on its own. Units that survive carry over, so a good early placement compounds while a bad one keeps losing the same fight repeatedly.

Unit tech upgrades

Reinforcement card drafts

Between rounds you pick from cards sorted into levels, from cheap level 0 options like Elite Marksman and Assault Fang up to level 3 cards like Nuke, Lightning Storm and Mustang Production Line. The usual advice is to skip anything below rare rarity unless it directly fixes your board.

Starting specialist selection

You choose one specialist from a pool of four at the start, and most hand you either extra supply or a free unit. Taking the free unit, especially a rare one, generally outperforms taking supply because it sets your opening board a round ahead.

Counter reading between rounds

You see the enemy board before committing your next purchase, and almost every unit is hard countered by something. Crawlers flood cheap melee that giants struggle to clear, Vulcan splash erases those Crawlers, Melting Point burns through giants, and Marksman range punishes anything slow, so the loop is watch, identify, answer.
