STR11: Tunnel (Stronghold: On the Edge of Chaos)

STR11: Tunnel is the eleventh map of Stronghold: On the Edge of Chaos. It was designed by Daniel Gimmer (Tormentor667) and uses a custom music track.

This level introduces the "Milestone" mode, where the objective is to stop monsters passing through a series of milestones on their way to the deadline.

Essentials
Before the level starts, Lt. Carmack will brief you on the essentials of the Milestone mode. The level itself is one long passage - monsters will spawn at the north-east end of the passage and follow it until they reach the deadline which is behind your starting point. Along the way the monsters will pass through three numbered zones - these contain the milestones that you need to protect. Each time the enemies breach a milestone, they will start spawning in that zone instead.

The starting room contains weapon, ammo and health pads; a powerup pad can be found in zone three. There are numbered teleporters in the starting room that will allow players to quickly travel to and from the zones - use teleporter one to reach the demons' starting point. Each time a milestone is breached its teleporter will be sealed.

As with Deadline levels, focus on the fastest enemies first before they get too close to the milestones; powerups may be required to hold back the cyberdemons that appear on the final wave. Watch out for the pain elementals on wave seven; if they fire a lost soul at you then it could go through a milestone by accident.

There is a shotgun and shotgun shells on your left as the level starts.

Completing this level will award 1,000 bonus credits.

Other points of interest
A marine reinforcement powerup can be found above the deadline - use the lifts either side of it to reach the powerup.
