This is a bit of a jack of all trades character that I didn't really like. His big bonus is the superior earnings ability and a lot of bonuses to critical hits. This makes them a fairly good character for a new player.
This is a good character to start with, especially since they should start out with a fairly good ally for free. The hunter's bowgun or rifle are also great weapons that should last for awhile.
This is for a shotgunners and I'm not sure that I would suggest it for a main character. Shotguns are very powerful, but you'll have to defend on other people for long range support once the game really gets going.
The militia soldier's real boost is that they can randomly toss out some free grenades onto the battlefield. They don't have many skills besides cutting enemies down though. If you really want to focus on explosives and big guns, then they're a good choice.
In order to unlock the Noble as a starting character in Elona Shooter, you have to level up a sheriff up to level 10. They're a true jack of all trades and can literally learn just about anything. They also have a 40% boost to experience earned, which really helps with leveling up. You'll actually have to work fairly hard at keeping the skills focused if you don't want to get bogged down in a bunch of useless first level skills.
In order to unlock the Ranger in Elona Shooter, you have to get a hunter to level 10. They're pretty useful with big guns and heavy weapons, but they are not anything too special.
In order to unlock the Duelist in Elona Shooter, you have to get a rogue up to level 10. They are incredibly useful. They can get a ton of critical hits and string together lots of kills. It's a great addition to any party, either as the hero or backup.
This is pretty self explanatory. You need to get a militia soldier up to level 10 to unlock the sniper in Elona Shooter. They're a good shot and if you upgrade them with a sniper rifle and some decent mods, then they'll be really useful. Make sure you have someone with Leadership though, or else they'll aim way too slow.
This is only a recruit class, but it has a nifty skill. They can flat out negate damage to the castle with a percentage depending on the level. They are also good with shotguns and can learn some useful skills.
