well im not very familliar with ut2k3's gameplay either, but when i look at the mazon remake, i dont really need to be to be able to see that its awfully designed.
at the start you have 3 autocannons which are permanently fireing, you can only attack via chains, you cant launch, the last bit to the chains you have to swim and you can only leave the water at 2 spots. the defenders have rocketlaunchers, shockrifles, snipers and a redeemer. i mean wtf?
then once u made it past the chains you have to get to the 2nd level which u can only reach over a single slow lift.
this map is unplaybale and so are basicly all others. i guess the coding of the mod is good from what i can see but before someone releases some decent maps you can save the downloadtime.
