Infiltration is a GDI covert operations mission that pits the player in controlling a single Commando against groups of Nod forces concentrated in four sectors.
GDI Covert Operation:
Secure this underground facility by locating and destroying all Nod CONTROL CENTERS. You only have one combat unit available, the COMMANDO.
The facility is divided into multiple sectors. Destroy the Control Center of each sector to gain access to the next sector. Be warned, each sector is more difficult than the last.
If the Commando dies, you will fail the challenge. Good luck.
