Last Armageddon is a painful-to-play atrocity of an RPG, but it seemed to have a heck of a lot of potential when I first got going with it. I found it to be very reminiscent of Efera & Jiliora (another Brain Grey title and a personal favorite of mine) in a lot of ways: E&J's narrator, some of its sound effects, and many of the browns and greens that dominate its unsettlingly bleak canvases are also employed here.
As if it isn't awesome enough that your party consists of fantastic creatures of legend instead of the usual run-of-the-mill RPG good-guy types, said creatures actually evolve into tougher, fiercer, scarier aberrations as they level up, eventually reaching points where they can merge with other beast types to acquire additional attributes and powers.
Many of the monsters can make use of specific types of armor and weaponry, and the system implemented for purchasing such goods is pretty interesting. Basically, certain members of your party can acquire equipment, healing items, and status-effect relievers whenever you want them to, which is obviously very convenient, as is the constantly available save-game option.
But bear in mind that you can have only one save file going; don't save yourself into a bad position! And bear in mind that this is merely one of the many negatives that plague Last Armageddon, and just by playing the game in the first place, you're putting yourself in a very, very bad position.
And it's ridiculously easy to break the entire gameplay system. With so many random battles to participate in and so many enemies to slaughter, it's only a matter of time before at least some of your monsters develop into such fearsome powerhouses that they're completely impervious to harm. The second time I defeated the game, I put more effort into achieving balance among my party members and made sure to take advantage of situations that allow for quick, painless experience acquisition; and following a routine early stretch of leveling, most of my monsters didn't take a single point of damage the rest of the way.
First of all, note that you won't be able to view certain cinemas in their entirety (and thus will miss out on key items) if you aren't using the "correct" party at the points where the interludes play out. You'll usually want to be in command of the gargoyle party when a cinematic moment is about to go down.
Hang out around your home base for a while and level up. Once your creatures have built up some muscle, venture out to find the four enemy outposts and kill the boss at each one. You'll acquire the ID Card.
Once you've had your jollies at the expense of the hapless outpost crews, head northwest to the ice area and enter the dungeon.
On the seventh floor, you'll finally get to face the boss of the tower. Then you'll be done with it.
There is a town to the south and a tower to the northeast, but you can't enter either of them yet. You need to enter a factory first. It looks like eight white "squares" set up in two rows of four. Enter it through the lower-left square.
The fifth floor has LOTS of teleporters on its walls. Take the wrong one and you'll find yourself back at the beginning of the floor. Have fun.
