Well, let me begin with the good. First, the map is gorgeous. The author uses the abilities of the Legacy port to full advantage to render a wonderful 3d environment that makes the battles all that much more interesting because the attack can be coming from anywhere. Also, lighting is quite nice. And, for the most part, gameplay is excellent, if a little linear. The battles are tough at times and something is continually getting sprung on you but as he says in the text file, you can duck and shoot. It's all good.
Now for the bad. For the second map in a row I am frustrated by an author who does not take into consideration his audience. I mean, I've got nothing against a good battle but the last room and the exit hallway are simply ridiculous. Look to the left at the picture and that is the room you find yourself in just before the exit hallway. At this point in the game, you have run low on health (and ammo). You are in a big room with lots of crates and chaingunners sniping at you from various points throughout the room. Because they are at a distance, it is difficult for YOU, the player to get a bead on them before they flatten you but if you do manage this Herculean feat, you will move into the room and IMMEDIATELY find yourself surrounded by dozens of those goddam flying skulls as well as imps, etc... and you must recover the yellow key. At this point, you are running around like mad trying to get some health and ammo and you discover that you can't simply shoot because you have attacks from multiple directions at once. So - you run for the yellow door with all due haste and open it (provided you accidentally came across the yellow key in your pellmell run for survival. What do you find waiting for you? Take a look at the picture at the top of the page. Not one, not two, but THREE Atchviles await you in this slim corridor and all the beasts of hell are at your back. Even with a full charge in my plasma gun - there was simply no way to defeat this. THREE of them? Are you f'n kidding me? One I can see. As long as you held on to some plasma ammo you're ok. But three? It only takes an attack from ONE to seriously F up your day.
