Radiation was originally an incredibly small Halo 3 map made by me, suitable only for doubles at the very most, or truly insane mosh pit games. That map, however, was not at all like my original intentions, and retained only the smallest part of the original conceptual design. For Reach I decided to rebuild it as the original designs dictate, and this is the result.

Overview:

Radiation is a small, symmetrical map designed for competitive team-based play. While most game-types are supported the most enjoyment to had is in symmetrical objective and team-based slayer games, though free-for-all is entirely playable and can be quite entertaining. Here follows a number of images showing the map, with brief descriptions. Further written descriptions can be found after the images.

Red base observation room, which is the objective room in assault and CTF:

The walkway connecting red base and green tower:

The Sword room. Believe it or not this was almost the entirety of the original Halo 3 Radiation:

In the centre of the map on the main level is a rocket launcher which spawns with two rockets. Below this on the lower floor is the sword room which, predictably, contains an energy sword. To access either of these locations one must go via either orange or green tower, each of which feature three levels, with a DMR on the top floor and two fragmentation grenades and a health pack on the bottom floor. There is a man cannon on the bottom floor of each tower which takes a player to the top floor.

Each of the towers is connected to both bases by a walkway, and each walkway has two plasma grenades spawning on them.The walkways between the bases and towers come in two flavours - high and low. High walkways connect the red base to the orange tower and blue base to the green tower, enter the tower on the top floor and have a pistol spawn on them. The low walkways connect the red base to the green tower and blue base to the orange tower, enter the tower on the main floor and have an assault rifle spawn on them in addition to the plasma grenades.

The bases themselves have two floors, the main floor which is larger and has a lift near the back which leads up to the smaller top floor, which contains a DMR and serves as the objective location in most objective game-types. The bases have lots of glass on their frontages so can be seen but not fired into. This is maintained by having shield doors protecting the base entrances, to deal with the grenade spam into the spawns.

A note on the special effects used (next gen and juicy) - I used these as they don't darken the map too much but combined make the colours of the buildings much more obvious, improving player orientation, which has to be done by the map itself rather than the backdrop in this case due to the encompassing walls.

I give you an action shot:

Anyway, I am entirely open to suggestions for improvements and welcome any constructive criticism. A link is provided below for anyone who is interested in looking at the original Halo 3 version of Radiation. I hope you have fun with it, Decho.
