The As in the original Nebulus, Pogo (a small green blob with no arms) must make his way to the top of the slowly rotating towers and claim them back from the evil Uncle (!). Once he has achieved this, he has to make his way back down again to repair all the damage inflicted by that Uncle. As long as Pogo reaches the bottom, he then hops into a chopper and flies off to the next tower, via the obligatory bonus stage. The bonus stages can be with Pogo flying with a kind-of-chopper through clouds and collecting bonuses while avoiding enemies, or Pogo travelling with a little sub underwater, again collecting bonuses and avoiding underwater mines and other hazards, and even Pogo riding as a cowboy a kind-of horse (!) in a ground tour to collect bonuses and avoid hazards such as pits and deadly rocks. Nebulus 2 offers a total of 8 towers full of nefarious monsters. All manner of weird creatures inhabit the towers and no two towers are ever alike too. Fortunately there are several power-ups here (in contrast to the initial Nebulus title) which include jet-packs that rockets Pogo round the tower killing everything in his way, magnets and jumping boots that lift Pogo to certain platforms etc. The towers have some doors locked too, so Pogo must find certain keys in order to unlock and get through.
Much like the original, contact with monsters doesn't kill you, it just knocks you off your perch and send you down a few platforms (which is rather annoying if it took you 10-20 minutes to get up there!). A pretty good game, with unique gameplay, nice visuals but tough to play at times.
The graphics are really tasty and very colorful with plenty of variety. In fact they are too colorful and you may easily notice that way more than the standard Amiga 32 screen colors are used here. Actual screenshots showed 80 to 110 colors on screen which is rather impressive! Scrolling is fluid and helps to make the game easier during gameplay. The flying, ground and underwater stages are very nice too, offering classic 2D horizontal scrolling gameplay, again with some impressive numbers of background color shadings.
Sound is good, bright and crispy with some sampled SFX such as the atmospheric howling winds the higher you go up, the lifts clank and creak, the magnets hum and give off metallic clangs when they hit a platform. Unfortunately there is no in-game music in the tower stages but only at the bonus stages, whilst there is a nicely composed introductory tune at the main menu.
