They are called the FRAX!!
Here is my version of Aliens/Xenomorph/Tyranids for use in Wardogs, with a few house modifications:
Antenna: Treat as Enhanced Sensors, but are not degraded by ECM.
Bio-ECM: Causes an effect similar to ECM, except that it affects the crew only. Per Level, -1 to Lock-on rolls but does not affect the bonus from Enhanced Sensors.
Egg sacs: Treat as Infantry Compartment (1 squad).
Hive-mind: Treat as a C3 system and as a T.A.R. to all other FRAX-units on the board.
Secondary Brain: Functions the same as the Co-pilot/Gunner.
