Bringing the thread back from the dead.
I got Alter Echo today. Apparently, if you can manage to find it, it's in the bargain bins now. But it's a bit difficult to find. Only one store in the local area had a copy. My thought is that after it was panned by critics, THQ didn't make any more of them.
I didn't catch the Descent reference in the intro sequence (other than that Proteus looks a lot like the sun on Descent 3's title screen), but there are some subtle hints of Descent here and there. In the manual, Paavo (the evil shaper) designed a cruise ship for a rival corporation that he subsequently vaporized. The cause was a "freak" reactor malfunction.
Of course the weird, skewed techno music of Jerry Berlongieri makes it feel Descent-like. Except for I think his music is definitely more at home here, with the strangely abstract, organic environments (the planet, Proteus, is living, you know).
It's actually a pretty decent game with a number of cool and interesting gameplay ideas. It's a third-person adventure with similar controls to Jax & Daxter or Ratchet & Clank. The idea here is that they merged this with a fighting game-style combat system where you can link together moves by pressing buttons in the right order. In a vague sense, it's like if you took Xenogears' combat system and made it real-time. The main moves, as Nevin (our sardonic hero) in his sword form, are a weak attack, a strong attack, and a juggle that flings the enemies skyhigh. You can mix and match these in many combinations, and execute them while jumping as well. You can also double-jump.
There are three different forms that almost correspond to Pyro/Magnum/Phoenix. Nevin's "sword form" is the default with average abilities in speed and attack. The "gun form" is a hulking mecha-like armor that moves slowly, but packs a wallop with its plasma gun and grenade launcher. Lastly, the "stealth form" is lightning quick and can use special paths, but is physically weak.
There's also "time dilation" which is a clever little minigame. Nevin can temporarily freeze time and render the battlefield as a grid. The idea here is that you guide a cursor through a grid of icons representing enemies, traps, and so forth. If you manage to connect several enemies and complete the puzzle, you are treated to a nice cutscene of Nevin destroying all of his adversaries in accordance to the minigame.
The game also comes with several bonus features. Aside from the game trailers and a psychedelic music track with visualization, there is also a "Making of Alter Echo" movie featuring snippets from Matt Long, Andy Crosby, and other ex-Outragers. There is also footage from the modelling tools from the artists that somehow made the hideous purple/yellow color scheme look cool.
I'd say the game is rather clever. It's not exceptionally polished or more fun than Ratchet & Clank, but it's better than a lot of similar games and definitely a fun rental.
