Mastering Gundam Assemble Rules: Your Complete Tactical Core Guide

Learn essential Gundam Assemble rules, timeline management, combat mechanics, and squad building to dominate every tactical skirmish and scenario.

Stepping into the cockpits of legendary Mobile Suits requires more than just raw firepower; mastering the intricate Gundam Assemble rules is the ultimate key to tactical supremacy on the tabletop. Whether you are reenacting cinematic story scenarios or engaging in fast-paced tactical skirmishes, understanding the core game mechanics determines whether your squad claims victory or gets sent back to the repair bay.

Let's dive straight into the foundational systems that drive this miniatures combat game.

The Timeline (TL) System and Turn Structure

At the heart of every match lies the innovative Timeline (TL) system, which simulates the relentless passage of time during combat. Unlike traditional alternating turn structures, units act according to their positions on a 10-space Timeline track representing the rounds of a Phase. Each game typically spans two phases of 10 rounds each, making every action count.

When you declare actions—such as moving, advancing, energizing, or attacking—your unit incurs a Timeline cost. This cost forces your Timeline token forward on the track. If a token exceeds space 10, it loops back to space one, potentially pushing your unit into the next phase.

Timeline Action	TL Cost	Effect / Description
Advance	Free (Standard)	Move up to 3 hexes (modified by terrain/engagement).
Dash	2 TL	Move up to 2 hexes quickly.
Energize	2 TL	Gain 1 Energy token placed on your unit card.
Rescue	2 TL	Rescue an adjacent allied Garrison for 2 Victory Points.
Attack	Variable	Pay the weapon's specific TL cost to initiate combat.

Managing your Timeline tokens efficiently prevents your high-value Mobile Suits from stalling out while enemy factions control the board. Player experience shows that staggering your unit activations prevents leaving your frontline defenders completely isolated on the track.

Squad Building and Tactics Deck Construction

Before hitting the battlefield, players must carefully construct both their Mobile Suit squad and an auxiliary Tactics deck. Squad composition is usually dictated by your chosen scenario, typically requiring three or five units, sometimes paired with a massive Carrier like the White Base or Char's Musai-class battleship.

Squad building is largely open-ended across Gundam eras, but it comes with strict deck-building constraints. Your Tactics deck must consist of exactly nine cards, and you can only include one copy of each card. Furthermore, inclusion is governed by specific rules:

Deck Building Rule	Requirement	Limitation
Signature Cards	Matching Unit Title	Can only be included if your squad features that exact unit variant.
Faction Traits	Matching Trait (e.g., Zeon, Earth Federation)	Requires at least one squad member sharing the corresponding faction trait.
Deck Size	Exactly 9 Cards (Standard 2-Phase Game)	Expands by 3 cards for each additional phase played beyond two.

Community reports highlight that tailoring your Tactics deck to leverage your Mobile Suits' specific faction traits is vital for pulling off game-changing response abilities and unexpected damage boosts.

Combat Mechanics, Line of Sight, and Accuracy

Engaging enemy Mobile Suits is where games are won and lost. The combat sequence follows a rigorous step-by-step resolution protocol, starting with declaration and weapon selection, moving through dice rolls, and culminating in damage calculation and status application.

When choosing a target, your unit must be within weapon range and possess a clear Line of Sight (LoS). LoS is determined by drawing an imaginary line from the center of your unit's hex to the target's hex.

Obstruction Type	Same Elevation	Different Elevations
Terrain / Elevated Ground	Blocks LoS if higher than both units.	Blocks LoS if equal to whichever unit is higher.
Enemy Units / Bases	Blocks LoS if at the same elevation.	Blocks LoS if at the higher unit's elevation.
Allied Units / Garrisons	Does not block LoS.	Does not block LoS if on lower ground.

Attack Rolls and Modifiers

When you fire a weapon, you roll a number of 10-sided attack dice equal to the weapon's Strength value. By default, any die showing a 4 or greater scores a hit. However, environmental factors and elevation heavily influence your accuracy:

Modifier Source	Effect on Accuracy	Notes
Higher Elevation Target	-1 Accuracy	Subtracts 1 from each die roll (excludes 1, 9, 10).
Lower Elevation Target	+1 Accuracy	Adds 1 to each die roll.
Water / Debris Fields	-1 Accuracy	Applies when attacking into or firing from these terrains.
Minovsky Particles	-2 Accuracy	Applies to non-adjacent attacks involving particles.

Natural rolls of 1 are always automatic misses, while rolls of 9 or 10 score critical hits that bypass accuracy penalties and trigger devastating weapon effects.

Status Effects, Upgrades, and Terrain Hazards

The battlefield is rife with environmental hazards and tactical modifiers that can swing momentum instantly. Applying status effects or collecting map upgrades can mean the difference between glorious victory and complete destruction.

Status effect tokens are placed directly onto unit cards and remain until triggered:

Status Effect	Trigger Condition	Mechanical Effect
Disarm	Next attack resolution	Must reroll all successful hit dice and cannot trigger critical effects.
Fracture	Taking 3+ combat damage	Takes an additional 3 damage immediately from the attack.
Slow	Next Advance action	Mobile Suit moves 0 hexes during that Advance.

Collecting Upgrades on the Map

Units can collect Shield, Speed, and Strength upgrades by ending a movement action on a hex containing upgrade tokens. Shield upgrades provide active protection against incoming damage, flipping face down when preventing hits and refreshing at the start of your next activation. Meanwhile, Strength upgrades permanently bolster your attack dice pool for the remainder of the skirmish.

Victory Conditions, Objectives, and Garrisons

Surviving the skirmish is only part of the battle; scoring Victory Points (VP) is what secures your triumph. Scenarios define specific mission goals, but standard VP sources include:

Objective Type	Action Required	Reward
Enemy Mobile Suits	Reduce hit points to 0	VP value printed on the defeated unit card.
Enemy Garrisons	Defeat auxiliary forces	2 Victory Points.
Allied Garrisons	Rescue adjacent garrison (costs 2 TL)	2 Victory Points.
Battlefield Objectives	Control / Contest at phase end	VP rewards dictated by the active scenario goals.

Contesting objectives requires ending your activation on or adjacent to an objective marker with a superior number of allied units compared to your opponent. Mastering these territorial control rules ensures your squad accumulates points even while locked in fierce skirmishes.

Frequently Asked Questions

How do Gundam Assemble rules handle unit deployment?

Players begin with their units stationed in Reserve rather than on the board. During your unit's very first activation, you must deploy it from your base or carrier hex. Once deployed, the unit activates immediately, though it must move at least one hex before ending its activation.

What happens when a Mobile Suit is defeated in combat?

When a unit's hit points reach zero, it is removed from the board, returned to its owner's Reserve, and its Timeline token is moved two spaces forward as a repair penalty. Its hit points and status effects are reset, but any accumulated energy or upgrades remain intact until it redeploys in a future round.

Can units jump over obstacles and enemies during movement?

Yes! When a unit begins a move action while positioned on elevated terrain, it is considered to be jumping. This allows the Mobile Suit to cross gaps in terrain and ignore enemy units positioned at lower elevations, provided it pays the normal movement costs for changing elevation levels.

How do you score victory points in Gundam Assemble?

Players earn victory points by defeating enemy Mobile Suits and garrisons, rescuing allied garrisons, successfully capturing and controlling key map objectives, and fulfilling unique scenario-specific mission goals across the game's designated phases.
