Xenon 2: Megablast takes up the battle straight after the original Xenon wars. The Xenites had no option except that of retreating and regrouping, but they are threatening to disrupt the dedicated balance of time. They have returned with a plan to wipe out the player's history by planting four bombs in space-time areas. It is up to you to blast your way through five levels, eradicating the oncoming Xenite forces. Each level depicts a different time zone in Earth's evolution, and the Xenites have armies in each of the zones which, if you fail to eliminate fully, will irrevocably alter our history! The enemies are mostly various nondescript organic creatures, plants, bacteria-like lifeforms, though the final levels feature robotics, mechanical enemies, and various artificial hostile entities.
The game relying heavily on power-ups, which may be gained by shooting power-up containers that appear. When an enemy (or a wave of enemies are destroyed) will also leave behind credits in the shape of bubbles which can be used later at a shop to buy (or sell) more fire-power. The shop appears mid-level and at the end of the level.
Unlike the craft you piloted in the original Xenon, this ship cannot transform into a tank, but now it houses more facilities for extra weapons.
Although a well polished shoot em up, the action is just seemed too frantic and at times, gameplay becomes rather frustrating. Of course there are a few flaws in gameplay, especially with collision detection here, but these objections are thoroughly trounced by the simple experience of it. Xenon 2, like the original Xenon, is tough, but it plays extremely well, and knocked back then many contenders to its throne straight out of the skies!
The graphics are superb here although running only in 16 colors on screen (rather awkward for an Amiga game). The three-layer parallax scrolling and the organic-style graphics certainly live up to the hype. The screen scrolls extremely smoothly, bringing with it wave after wave of superbly detailed aliens and backdrops. The end-level guardians are really something too!
The game features a David Whittaker version of Bomb The Bass' Megablast - Hip Hop on Precict 13 Mix music. During gameplay, this tune suits the game perfectly. There are several sampled SFX of explosions, laser-firing etc. I found the Amiga music more appealing though when compared to the Sharp X68000, probably due to the faster tempo found in the X68000 version which sounds to me a bit awkward when compared to the original tune. But unfortunately, due to the 4 channel sound limitation here, half of the music channels are skipped when SFX come in.
