MAP09: Stronghold is the ninth map of TNT: Evilution. It was designed by Jimmy Sieben, with minor additions and touchups by Ty Halderman, and uses the music track "Sadistic". It is notable for having many enemies. This sheer number of monsters almost entirely consists of hitscan-employing troopers, sergeants and chaingunners, who will often take potshots at the player from balconies and through windows. The somewhat confined layout of the map also adds to its difficulty.
