They’d never do this but I think it would be a really cool sequel if you could play this game front the Tyranid perspective.

Imagine if you played as a sort of avatar of the hive mind or a facet of it. You warp into the swarm’s command unit and fight while issuing broad instructions that directs the swarm.

Your “lives” are the amount of command units in the swarm that are available. Die once and warp out of the dead command unit and into the next up until the swarm is out of command units.

The upgrade tree would be pretty easy: you get better commands as you level up and you get auras or global unit bonuses that reflect whatever exists in the tabletop game. I guess you could probably “summon” reinforcement units from underground and get better command units as you progress too.

The game could switch between swarm battles and solo missions where you have to do things like infiltrate or by other conceits of the narrative, such as breaching through the walls of a compound with the swarm and then on the next level inside the compound there’s a terminator or something that just obliterates your underlings, leaving you to duke it out with them 1-to-1 before proceeding through the compound solo.

Having to balance between commanding, staying back and using ranged attacks, or playing as the tip of the spear would allow for different play styles and it would be challenging because you would have to adjust your strategy to be most effective.
