Level Guide

In the full game of Warblade, there are a maximum of 100 Main Story Levels. There are also 5 Special levels that are accessible through special means. Upon completing level 100, you get to view the End Game Credits and the one-hundred levels loop over, but this time with increased enemy bullets and speed, with the enemies attack patterns flipped horizontally, and some additional player content.

Level Layout
All the levels in Warblade (except the 5 Special Levels see below) follow a simple theme. They go as follows: All the levels fix into this scheme. Every 4 levels repeat the theme until level 25 where you face a mid-boss. Then the whole level pattern repeats again.
 * Level 1 and 2 :: Small Aliens
 * Level 3 :: Small Aliens and Mother Alien(s)
 * Level 4 :: Kamikaze or Bonus (alternating each time)
 * (warp)
 * (level 1-4 repeat)
 * Level 25 :: Mid Boss
 * (level 1-25 repeat)

In-Level Scripts
Throughout the game, each level can be categorized by 3 main types. The majority of the game levels are the Kill All, making it harder to progress further with an insufficient weapon and/or lives. The Bonus levels are typically Hit & Run as the challenge is to defeat as many as you can.
 * Kill All - You must kill all the aliens to progress
 * Hit and Run - The aliens will attack you but then leave, allowing you to progress.
 * Kill and Run - Some aliens will hit and run whilst some need to be killed (both of the above 2)
