Rally Point

Rally Point is a Firefight map in Halo 3: ODST.

Universe and lore
"Sector 10 inside the city of New Mombasa has seen better days. The air is heavy with acrid smoke parted only by the constant arrival of enemy drop ships. Lucky for you, the crossroads that converge on the entrance into ONI’s Alpha Site offer up a textbook choke point. The Covenant has come to claim access. You and your squad of ODST’s are going to stop them at all costs."

- Bungie.net description.

Rally Point is set in New Mombasa Sector 10; the New Mombasa island's southmost point aside from the Alpha Site. During the Battle of Mombasa, the area was used as a rally point for UNSC and NMPD forces being pushed back by the Covenant, intended to regroup at the Alpha Site. In the Halo 3: ODST campaign, this area can be encountered in the final defensive section of the level Kizingo Boulevard during the day, and as part of the open world Mombasa Streets at night.

Layout
Located in the center of New Mombasa, it is a small, asymmetrical map and features uneven terrain, with a network of roads and walkways around the entrance to the ONI Alpha Base. Phantom dropships are able to drop Wraiths onto the map. The battlefield slopes upward towards the building, allowing a player to get a decent view of the enemies, while walkways connect different areas of the map.

Strategies

 * A certain glitch can be used to drive the Wraith on this map, making much of the defense easier to manage.

Rally Point (Night)
Due to its geometry being shared with both a campaign level and the Mombasa Streets hub-world level, Rally Point is one of two maps (alongside Crater) to also receive a night variation of the map. The night variant features identical map geometry, with the primary difference being the night-time setting of the map as opposed to the afternoon setting of the standard map. The night setting imposes an additional challenge on the player, requiring more use of the VISR. The night-time variant features a number of small changes, including;
 * Engineers spawn instead of Sniper Jackals
 * Pupal Drones may spawn alongside their regular brethren
 * The doors to the ONI building are closed.

The night variant of Rally Point otherwise features no differences from the standard version.
