Seven old levels (most from 2001) packed together; six Conquest levels and one Warfare levels. I planned to make a new 8th level but I lost motivation so I'll leave it like this. With Vegito's aid, I implemented the relatively new teambattle systems in the Conquest levels, so playing with 2 teams will be more "automatically", although I left the original versions in as well (for playing with 3 or 4 teams; which isn't recommended).
These two concepts deserve some explanation. I'll quote:

Conquest:
"First you have to divide the players in teams. The first six levels all have two versions. One for two teams (recommended; should be hosted in CTF), one for three or four teams (should be hosted in battle). The problem with battle is that members of a team can also shoot eachother, and this creates serious problems in Conquest. Choosing which team you want to play in is done by choosing and going in a hole. Then, each time has to decide who they want as king/leader. If there are only two teams, the leader of each team will get a flag.

When all the decisions are made, it's time to start the game. Traditionally in my levels, although this is not neccesary for the concept to work, each team starts at their own castle/base, where they can pick up ammo etc.
The objective is to kill the enemy team's leader. If hosted in CTF, everytime you kill him/her, your team gets a point (thx to Vegito for fixing this part). However, if played in battle (with more teams), there is no clear way to keep track of the scores, so you will just have to memorize it or play sudden death mode.

However, there is a catch. When players die, they will end up in a jail, where they will have to be freed with ice by their teammates. It's vital that you get your teammates out as fast as possible, because they need to defend the king and at the same time hunt down the other leader(s)! Naturally, the leader won't end up in the prison after being killed. Of course, there are also Conquest levels without the jail system."

Warfare:
"First, every player chooses his or her "job", you can choose between;
- King/general (orange)
He can only stay in the king's room and shoot down ammo for the knights and ninjas
If he's/she's killed, the other team wins
- Knight/Warrior (green)
Can leave the castle for the battlefield
This is the only job wich can invade the enemy's castle and kill the king
- Ninja/Scout (gray)
Can use the underground network and gun9 to kill enemies above it
- Guard (yellow)
Should guard the king with his/her life, can help with shooting down ammo
Can walk through the castle but can't leave it
- Dragoon (indigo)
Can fly through the battlefield
Can't enter castles or caves
To play the game, you need at least a king and a knight for the blue team and a king and a knight for the red team. The goal is to reach the other castle, and kill the king in there. Each castle can have some obstacles in the way, or puzzels with triggers to make it harder for the enemies to reach the castle and kill the general."

Because the filesize would get too big otherwise; I cut the pack in three parts.
