We start in a new environment, completely different and large with its many rooms. I took screenshots below on the initial map 01. Since there's no introduction for the new mission in the second stage, I was wondering what kind of place this could be, it could be a factory because of the textures?
Here, the enemies change. They are these gray silhouettes resembling humans used as "placeholders" until the devs create final art and animation. They leave Rifle ammo on the ground and are dangerous at a distance. I lost a percentage of the bulletproof vest, as you can see. There's only one elevator as a way to proceed.
So, I return to map 02 via the central elevator, then go to the southern elevator, reaching another large section to the east of map 01, with an elevator to the north. Fearing I might leave something behind in the elevators of map 02, I go back and head for the western elevator. On map 03, I decide to explore it all and go all the way to the end before returning. This is where another item appears, the Flashlight, which is very helpful compared to the previous game, as you can see below.
Leaving map 03, I reach map 05, which turns out to be a huge map with long corridors and wide rooms.
Other items appear here, like the Night Vision, which is more of a hindrance than a help in this stage and finally, 2 Bullet Proof Vests. I spent a lot of time on map 05. I found only one elevator in the north of the map and decided to keep going forward instead of returning, as I did in the eastern part of map 01.
Upon taking the elevator, I end up in map 06, which to my surprise, was the only map completely empty of enemies and with a strange design, making me believe that inside that square room with two entrances or exits, there would be another Boss or the map was simply unfinished, because it didn't even have any enemies. So, I return to map 02.
So, when I shot one of these cracks, a secret room was revealed and in other cracks, there were corridors leading to other rooms with enemies. Most of these secret areas have ammo for the best weapons in the game, so they are essential for players to avoid difficulties.
I decided to look it up and found a YouTube video titled "Beyond Zero Tolerance | Sega Genesis | New Prototype (Jul 14, 1995)". In the description, he explains the lack of the Boss in stage 02, but it seems there's more content, including two more stages. He named stage 02 "Base on an alien planet". And by watching his video, I discovered that the destructible walls in stage 01 have this rectangular detail in the texture. Also, when throwing grenades in the Boss room in stage 02 on map 06, a dead body appears and then it transitions to a new stage.
I believe this YouTuber must have accessed the game's internal files and discovered the passwords for all the maps to reach the other stages of this prototype, because after the 5:18 mark of the video, he starts in stage 03 with little ammo, which makes me think this is the case. In stage 03, there are female aliens as enemies, a white silhouette and cocoons that release small aliens when shot at. Could this be a reference to the Alien franchise? These textures are completely intriguing, looking like a base underground inside caves. I was really excited to play until I saw that the devs left shortcuts at the beginning of each map in every stage to test them, I imagine. So, I decide to return to the beginning in stage 02 and go back to map 01.
