I'm now on staff at the Action HL Map Depot. I just did reviews of four maps, see if you think I did a good job:

If you have any good HLDM maps that you would like to convert to AHL, let me know. I'll let you know if the map would play well in AHL. Generally, AHL maps need a bit more open space in corridors etc. because of the stunts and faster movement rate. And it's better if it's easy to find other players, since AHL has rounded modes as well. I can give you advice in the conversion, too, and guarantee you a review on the AHLMD when it is done.
AHL can run HLDM maps okay, anyway, (conversion is just preferable) so I might review them occasionally anyway, although I won't add them to the map database. Anyone have some recommendations for maps that would be especially good in AHL?
