What are some of your personal favorite Halo maps (Campaign, Firefight, Multiplayer)? Are there any under-used maps you think deserve a mention? I'm getting back into classic Halo CE and was wondering what some of the best maps there are.

The Takedown Series by MattDratt

Maps by Jobalisk, I'm a big fan of his stuff.

Bigass by aLTis is great.

Can confirm. Other maps to look into include Chronopolis, Hydrolysis, Immure, No Remorse, and Z Coagulation H2.

The Covert Ops campaign is a good singleplayer series.

> PS. Coldsnap, Extinction and Hugeass are popular, but I think they're too big and don't play very well, and they don't even look good artistically either.

Unreleased, but looked great. Dunno what happened to them:
- Halo Composition
- Takedown Extermination
- Sierra 117
- Heretic Hunt
- Forge for Halo CE
- MVM Mental & VKMT Multiplayer (Yeah, it was supposed to be a pack of what looked like excellent multiplayer maps)

IMO, some of the earliest (2004-2005) multiplayer maps were also the best, in terms of being fun and balanced to play:

- Claustrophobia
- Fissure Falls
- Cliffhanger
- Church
- New Mombasa Classic (H2 Updated was good too)
- Quagmire
- Frost
- Gallows Pole
- Yoyroast Island 1 & 2
- Nightcamp CE (IMO one of the most underrated)
- Needleosity (anyone remember this one?)
- Wartorn Cove (3 and 4 were best)

Single Player:
- Area 53/54 (not exactly impressive by today's standards, but worth a play if you haven't or its been a while)
- CMT SPV3
- The Silent Cartographer Evolved
- Firefight Descent
- Halo Covert Ops
