How to Start a Tyranid Army with Combat Patrol

Quick answer

Start with the Warhammer 40K: Combat Patrol: Tyranid box, build it in sub-assemblies, paint the swarm in batches, and play a few small Combat Patrol games before expanding. This gives you a legal, flexible force with a low entry cost.

Why Combat Patrol is the right starting point

A Combat Patrol box gives you a complete, playable force with a mix of unit types. For Tyranids, the Assault Brood includes a Parasite of Mortrex as leader, three Tyrant Guard, a Biovore for ranged support, and ten Genestealers for melee pressure. This variety lets you learn different playstyles without buying multiple kits.

The trade-off is that you get a fixed set of units. You cannot swap out the Biovore for more Genestealers, so if you prefer a pure melee swarm, this box may not suit you. However, it is an efficient way to get a functional army quickly.

Build for painting and gameplay

Tyranid models have many overlapping limbs and carapace sections. Painting them after full assembly can be frustrating. Instead, leave sub-assemblies for parts that are hard to reach, such as the Parasite of Mortrex's wings or the Genestealers' arms. Use a small amount of glue on joints and dry-fit before committing.

Also consider magnetization if you plan to swap weapons later, but for a starter force, simple assembly is fine. Focus on getting models on the table.

Painting Tyranids efficiently

Tyranids are forgiving for beginners because organic shapes hide brush strokes. Choose a simple scheme: a base color for the carapace, a contrast color for flesh, and a wash. Batch-paint similar models to save time. For example, paint all Genestealers together, then the Tyrant Guard.

Do not aim for display quality on your first army. A clean, tabletop-ready paint job is enough, and you can always add details later. The key is to avoid getting stuck on one model.

Learning the game with your new army

Combat Patrol is designed for small games, so you can start playing with just this box. Focus on learning unit roles: use Genestealers to tie up enemy units, keep the Biovore safe to lob Spore Mines, and position the Parasite of Mortrex to buff nearby units. The Tyrant Guard can shield your leader.

Play a few games against a friend or at a local store. Do not worry about winning; aim to understand the core rules and your units' strengths.

Step-by-step: Start your Tyranid army

1. Assemble the box in sub-assemblies: Build the Parasite of Mortrex, Tyrant Guard, Biovore, and Genestealers, but leave arms and wings off until after painting. Use plastic glue sparingly and test-fit joints first. Check that every model fits on its base without overhang before gluing.
2. Prime and basecoat in batches: Spray-prime all models with a light color, then apply your main carapace color to all models at once. Use a wash to shade the flesh areas. Avoid spraying in high humidity or direct sunlight to prevent fuzzy primer.
3. Paint details and finish bases: Paint the weapons, eyes, and other details, then attach sub-assemblies. Add texture paint and tufts to the bases for a finished look. Keep a note of your paint colors so you can match them when you expand.
4. Play a Combat Patrol game: Set up a small battlefield and play through the core rules with just this box. Focus on using each unit's special abilities, like the Biovore's Spore Mines. After the game, note which unit performed best and which felt confusing.
5. Expand with a second unit: Once you have played a few games, add a unit that fills a gap, such as more Genestealers for melee or a ranged unit like Termagants. Buy only after you have tested your current force. Ask your opponent what they found hardest to deal with; that often reveals your next purchase.

Key unit in this box

• Warhammer 40K: Combat Patrol: Tyranid: The Assault Brood is led by a Parasite of Mortrex, a swift creature accompanied by three Tyrant Guard, a Biovore, and ten Genestealers. This mix gives you a leader, a resilient bodyguard unit, ranged support, and a fast melee threat, so you can learn multiple tactics without buying extra models.
