Similar to Lockdown except the goal is to capture a single point located in a locked room.
Each map has exactly two capture points, one for each team. The capture points are located in a small enclosure with 3 or 5 sets of gates that can only be opened with keys. The enclosures are located on the enemy side of the field.
A team wins by capturing their point first (after unlocking all the gates). If no team captures a point in the time limit, the team with the most gates unlocked wins. If both teams have the same number of gates unlocked, it becomes sudden death and the team that unlocks the next gate wins.
Keys are located in various locations near the center of the map. At any given time, there are only enough keys to open the all the gates for one team. However, once a key is used, it respawns in the central location. A player carrying a key experiences a drastic movement speed reduction and cannot attack or perform any action (just like in clockworks). When the player carrying a key is hit the key is dropped in place. This happens even if the player takes no damage (ie. inside a guardian shield).
Maps should have many walls to increase potential routes for sneaking around enemies as well as hazards and perhaps monster spawns.
