Yes I remember the lone marine who got lost and dropped into Strogg stronghold and how he manages to break the Strogg from the inside picking up guns 🔫 & powerups to take out various Strogg soldiers & અરરોs one after another then making his way into palaces to take out the overlords who had all mutated with machines and weapons of mass destruction. They were all really very formidable foes, and once I defeated the Macron the whole planet got crippled and allowed for more invasions from Earth in the sequel Quake 4 where corporeal Kane with the allies is able to end the Strogg overlords while taking the damage of being mutated into a Strogg to further infiltrate and mitigate Strogg armies and bases on their home world. In the end I was able to destroy their capabilities of invading and endangering Earth.
