Lethal Xcess is an old-fashioned shooter. All the standard shoot em up features are include, much like its predecessor, and the two player mode adds a little more depth. You begin your flying-shooting voyage with (triangular!) simple laser cannons which can be powered up or exchanged for other as long as you shoot down enemy species, leaving you those candies! All in all there seven upgrades, all introduced by a digitized voice (i.e. "Drone", "Wiper" etc). The game is not an easy ride, and much like its predecessor, the incoming buddies are thick and fast. In fact most of the time the play area gets full of enemy bullets (eeehm laser staff etc) making you zigzagging all the time! Throughout the five (total) stages, the number of enemy sprites increase (!) whilst towards the end of each level there is always something BIG waiting for you... A good strategy is to try and pick one weapon and stick with it, since the more powerful, the more effective especially on the end-level boss.
Much like its predecessor, Lethal Xcess was a very good - not great - effort in the field of shoot em ups back to the days.
Ok the ST version offers good graphics (similar to the Amiga and the enhanced STE versions) without being absolutely exceptional. It is colorful using up to 30 screen colors using interrupts (same technique found for the STE version), nicely detailed screens and sprites while the game runs smooth. Using special sync-scrolling technique developed by Eclipse Software teams, nobody would have expected that the Atari ST was capable of doing a scrolling around 50 FPS game (also found in Wings of Death title). Sprites move quite fast here without the need of a Blitter chip (note that the STE and Amiga chipsets support Blitter and thus sprites move smoother when too many sprites occupy the screen).
Soundwise, the ST version (and STE, Amiga) is awesome, and continues to impress much like the previous game, offering a variety of nice tunes written by Jochen Hippel along with plenty of sampled SFX although not in stereo (only found on STE and Amiga versions).
