MechaStellar - Free Wargame Rules to Battle it out with your Favorite Mecha

Good afternoon everyone,

With the release of Hathaway's Flash today on Netflix I wanted to share a free wargaming rules set we have been working on the last few years. MAHQ & MechaTalk has been my #1 resource for everything Gundam & Mecha related since the early 2000s so I wanted to share with the community here for anyone who enjoys playing tabletop games.

The game is called MechaStellar and it's meant to be a lightweight d10 rules system to let you battle it out with your favorite Mecha. We've also updated it to include Kaiju and Stellar Warships as well. It can be played in a Vs mode or in a Solo / Cooperative mode (1-6 players)where you play against Missions where the enemy's actions are governed by a behavior table.

Mechastellar is setting-neutral, so it can be used with giant robots from your favorite series. Our goal with these rules was to let you use the rules to recreate iconic battles from your favorite series, create new or hypothetical ones, or mash several series together for a Super Robot Wars-esque game if you like. Currently we have units from Gundam (UC: OYW+0083, AU: Wing), Mazinger Z, Getter Robo, Evangelion (TV), Big O and Pacific Rim.

The rules for combat, versus mode, coop campaigns and mission packs can be download here: https://mechastellar.wordpress.com/game-downloads/

Since Gundam is our favorite real robot series most of the mecha unit profiles are from Gundam. Currently there are profiles for 160 Mobile Suits, 7 Mobile Armors, and 2 Warships.

If you get the chance to try out the game would love to hear your general impressions from playing. We're also looking for specific feedback in the below categories. Thanks for reading. Cheers!

======================BREAK======================

Edit: Trimmed down opening post.

Here are some key features of the game:
-Two Classes of Mecha.
A Mobile Skeleton (MS) that is humanoid and a Titan that runs the gamut of humanoid, bipedal tank, or bizarrely shaped mobile armor. MS focus on Evasion, Titans focus on durability.

A MS can be used to represent units from Gundam, Macross, Aura Battler Dunbine, Tekkaman Blade, or Zone of the Enders.
A Titan can be used used to represent Mobile Armors from Gundam or classic super robot shows like Mazinger, Getter Robo or the Braves series.

-Mecha are defined by only three stats, Frame, Performance & Pilot.
We're shooting for a lightweight rules system so it relies on abstraction and generalized weapon profiles rather than a lot of mechanical granularity. Combat stats are dependent on Frame & Performance.

Frame sets your starting durability and equipment slots, Frame 3+ units also receive a passive Performance boost.

Performance is a catch-all stat that affects combat stats, movement & sensors. Generally we treat suits that show up later in a series are higher performance than those at the start. For game balance in the OYW we typically give Zeon higher performance while the Federation has either multiple cheaper units or expensive high end units.

Pilot comes in two tiers, Level 1 is Skilled Pilots these can be test pilots, veterans, or someone with impressive natural talent. Level 2 is intended for your best aces like Amuro, Char or Norris Packard. An Ace even in a grunt suit can still be quite lethal.

-Two Gameplay Modes - Versus Mode & Cooperative Mode.

-Versus Mode
If you're familiar with other War Games then this should feel familiar. Assemble an army and battle it out with your opponent. Simple Battle is simply to destroy the enemy. Secure the Objective is your standard capture area objectives for victory points. Confrontation is for doing several short skirmishes back to back with repairs in between, you earn victory points for units surviving the conflict. We have Secondary Objective to be used in either format to give alternate ways of gaining victory points. You can play one on one or team battles.

-Cooperative Mode
We developed this during lockdown as a fun way to pass the time. You and your fellow player pilot a team of Mechs on various missions and grow your pilots as you progress. There's a simple behavior table you can roll on to determine what they do. Each mission pack will tell you what enemies you'll be facing and guidelines for how to set up the battle. You and your group have final say of course.

-Scalability
The ruleset can be used for small scale battles like three GM Customs vs several Gelgoog Marines. It can also represent much larger forces if you want to reenact famous battles near Solomon, Granada, or Odessa. Our largest battle so far had 20+ Federation suits and 30+ Zeon suits.

-Game Length
Cooperative mode missions usually run 20-40 minutes. Versus mode is usually 30-60min for a small game and 1-2 hours for a large game.

-Alternating Activations
Each round player's alternate taking turns activating one unit at a time. The round concludes once all units have activated. There's a Return Fire rule where you must activate a unit who was just attacked if able. This is for immersion so you see conflicts play out locally in large games, instead of trying to min-max the action/turn economy.

-Dynamic Mechs
Movement and Melee do not require an action. You can also move, then shoot, then move again.

-Ranged Combat
Only two die rolls are required to resolve a Shooting attack. One to see if the target Evades any shots and an optional Armor Save. Penetrating weapons like a Beam Rifle force an Armor Save and cause catastrophic damage if the target fails the save.

-Melee Clash
Updated in Version 8 to be more interactive. Melee allows both units to attack and defend against one another. Both sides roll their dice and count successes, each success from the defense blocks 1 success from the attacker, any unblocked hits get through and deal damage. Weapons like a Beam Saber have a high penetration value so even if a single hit gets through it has a chance of being lethal.

-Momentum System
Momentum ebbs and flows during battle and is primarily used to protect your units, it can also be used to deliver critical hits to the enemy. You can increase your Momentum by destroying units, attacking in melee and surviving each round.

-Production Values.
This is a small operation so nothing fancy. No artwork in the core rules. We wanted to focus on clear, concise and readable rules so we used bullet points extensively in the rules document.
