It was released on April 7, 2002. Essentially a retelling of the original game's Episode 4, the player is taken through 42 levels of high quality and with much variation. 37 levels are regular levels, with 5 of them being secret.
Coding features include the missile launcher, seamless level flow, end level objects, and on some levels (e.g. level 29) tweaks to pushwalls.
Some levels have a number of Hitler bosses on them, and in some few cases there is a shortage of ammo. Though difficult at times, the player is rewarded in plenty of treasure and easily accessible one-ups.
