First you need to trade over 100 bugfrag in the bugfrag trader to get him to show up randomly in black earth 2.He has 3,000 hp and his strongest attack takes 600 hp!! Yes he is hard unless you have 4 airhoc3 chips.This part is easy.all you do is wait untill he gets in the middle then you use it. You should get fullsycro.if you have two more on you then use them and you should be able to beat him.I beat him in 16.56 seconds.if you do beat him around my time you should get a giga chip call black barrier.
There are ghost navis in some certain areas of the net the one I can remember are Gutsman: ACDC 2 Topman:Town 1 Roll: Town 2 underpart. Searchman: Undernet 1 Laserman: Undernet five at random Shademan: Undernet four at random
Okay, I know a lot of people are having trouble on Duo, so here's how to beat him and dodge his moves. First off, you'll need the right moves. Pop Up and Invisable work really well. Plus Red Sun would deal about 300 damage normally. The Wind Soul will help you a lot because Duo breaks lots of tiles. Some moves won't hit Duo even if they're aimed for the red mark on his chest (which is his weak point). Which include moves like ColdMan, Flameline and Blizzard. The worst thing you could do is use Guard because if you do, you'll be a sitting duck (no, it won't block any of his attacks). Oh, and when you use moves like ThunderMan, Duo's chest is in the second row of tiles. Don't lose patience, it takes time and concentration to beat Duo. Now how to dodge his attacks. Duo will shoot landmines and missiles. When this happens, you have two options, either blow up the missiles (each missile has up to 50 HP) or be very quick and dodge them. There is an attack where Duo throw punches at you, if you're fast enough they're really easy to dodge. The punch when Duo slams his hand into the ground his a really good time to attack after you dodge it. If you don't know how to dodge it, the laser beam can get very annoying. Of course, you'll have to move to the side then you just have to watch where where the rings around the beam go. Jump over to where the rings used to be. If you do it right, the laser will miss you every single time. Now last but by all means not least, the attack where Duo flys fists everywhere. Now to dodge it, you need a very good eye if you don't have Invisable or Pop Up activated. Watch where his fists go then move to where he just punched(or you can just jump like nuts and pray you don't get hit). This attack is like lightning, it never strikes twice in the same place. Well that's it. Hope this thing helps you out. Now if you think he's scary at 2000 HP, every time you go to another game (game 2, game 3, so on, so forth), he gains 500 HP, so be prepared!
First of all, go to undernet 2 by jacking into the statue located in Netfrica. I'm sure that undernet 4 is the farthest you have gotten to (if you haven't been to undernet 6 that is). But in undernet 2, there will be another place you can teleport to get to undernet 6.The teleporting place in undernet 2 will be around the bottom. If you're going there to get S.Sensor, than talk to a black navi and buy it for 10000 zennys. So remember to collect money as yo go!
