Alternative sci-fi tabletop miniatures on a futuristic battlefield

5 Best Warhammer 40K Alternatives for Sci-Fi Wargamers

Warhammer 40,000 offers massive battles, detailed miniatures, and one of tabletop gaming’s most recognizable science-fiction settings. However, it is not the only option for players who enjoy futuristic soldiers, tactical skirmishes, imposing war machines, and creative miniature projects.

Whether you want customizable infantry, a smaller model count, narrative campaigns, or mech-focused battles, these Warhammer 40K alternatives offer distinct ways to explore science-fiction tabletop gaming.

Before you buy: These ranges have their own settings, rules, scales, and miniature designs. Alternative miniatures may be accepted in casual games, but players should confirm model dimensions, base sizes, and event rules before using them in organized play.

1. Wargames Atlantic: Death Fields

Best for customizable science-fiction infantry


Wargames Atlantic’s Death Fields range is an excellent option for hobbyists who want multipart science-fiction soldiers. The range includes military units, specialists, heavy weapons, and unusual factions that can support many different painting and conversion ideas.

Many Death Fields sets contain alternate heads, weapons, and accessories. This makes them especially useful for building custom regiments, creating role-playing encounters, or adding variety to independent science-fiction armies.

Why consider Death Fields?

  • Multipart hard-plastic miniatures
  • Multiple weapons and assembly options
  • Useful for kitbashing and conversions
  • Suitable for custom forces and independent games
  • Distinct military science-fiction themes

Because proportions and bases may differ between manufacturers, compare the selected models with your existing collection before combining them.

Recommended for: Hobbyists who want flexible infantry kits and plenty of customization choices.

2. Stargrave

Best for custom crews and narrative campaigns



Stargrave is a miniature-agnostic science-fiction skirmish game centered on small crews exploring a dangerous galaxy. Players create a captain, recruit specialists, complete missions, collect equipment, and develop their crew over an ongoing campaign.

Because Stargrave is not tied to a single proprietary miniature range, players have considerable freedom when building and painting their crews.

The Stargrave Troopers set includes 20 multipart hard-plastic 28mm figures, making it a practical choice for military crews, security forces, mercenaries, or other futuristic units.

Why consider Stargrave?

  • Build and personalize your own crew
  • Campaign-based progression
  • Terrain-focused skirmish battles
  • Lower model count than army-scale games
  • Multipart miniatures with customization options

Recommended for: Players who enjoy storytelling, character development, and freedom when selecting miniatures.

3. Halo: Flashpoint

Best for accessible science-fiction skirmish battles


Halo: Flashpoint brings the recognizable soldiers and battlefield action of the Halo universe to the tabletop. Its smaller-scale encounters make it a strong choice for players who want futuristic combat without immediately building a large army.

The Recon Edition provides a focused entry point for new players. It is better presented as a complete alternative science-fiction game—not as a range of direct Warhammer 40K substitutes.

Why consider Halo: Flashpoint?

  • Recognizable science-fiction setting
  • Compact skirmish gameplay
  • Smaller forces than traditional mass-battle games
  • Starter products and additional terrain available
  • Suitable for both new and experienced miniature gamers

Recommended for: Players who want an accessible skirmish game with military science-fiction miniatures and a familiar setting.

4. Warmachine

Best for powerful war machines and character-driven combat


Warmachine combines machinery, magic, and tactical battlefield decisions in the Iron Kingdoms. Its signature warjacks give players the opportunity to command large mechanical units alongside specialized troops and powerful leaders.

Warmachine has its own factions, rules, and visual identity. It is therefore better viewed as a complete tabletop alternative rather than a source of direct replacement miniatures.

The Orgoth Tyrant Heavy Warjack is a strong product to feature because its imposing mechanical design immediately communicates what makes Warmachine distinctive.

Why consider Warmachine?

  • Large and distinctive warjack miniatures
  • Strong faction identities
  • Tactical resource management
  • Industrial machinery combined with fantasy elements
  • Impressive painting and display potential

Recommended for: Players who enjoy powerful mechanical units, specialized characters, and tactical combat.

5. BattleTech

Best for tactical mech combat

If towering machines are your favorite part of science-fiction gaming, BattleTech provides a completely different battlefield experience. Rather than controlling large infantry armies, players command heavily armed BattleMechs in tactical engagements.

BattleTech emphasizes movement, positioning, armor, heat management, weapon ranges, and the individual strengths of each machine.

The Inner Sphere Heavy Recon Lance is a strong featured option because it shows several different BattleMech designs in one product image.

Why consider BattleTech?

  • Iconic BattleMech designs
  • Tactical and scenario-driven gameplay
  • Compact forces with distinctive units
  • Extensive setting and faction history
  • Numerous force packs and starter options

BattleTech uses a different miniature scale from Warhammer 40K. Its models are best enjoyed in BattleTech or other scale-appropriate projects rather than as direct replacements for 28mm infantry-scale models.

Recommended for: Players who want tactical battles centered on giant combat machines.
