Unfortunately, at that time – 1993 – there were also Super Mario All-Stars and Kirby Adventure, which pushed the genre upwards, meaning that Snake Logan’s platform, shooting and adventure exploration seemed like a failure when it came to light. Have you ever heard of Mario Sense? How can you see a particular screen in Nintendo’s flagship series and know where to find hidden things? Biothreat tickles the nerve endings themselves. And you’ll need these secret objects because it’s difficult. The gameplay is also a bit old-fashioned; in a world where Sonic the Hedgehog 2 already existed and Donkey Kong Country wanted to change the game, Bio Threat seems even more archaic. After a catastrophic mutant invasion, Snake Logan, a soft-headed mega star, must jump through city blocks, forests and underground bases in search of captured hostages. This doesn’t mean “he” would protest against the re-edition of Bio Threat that has eliminated its most annoying features – a button to change weapons and types of grenades, for example – but as initially presented, it’s a very nice piece of DOS. There’s a coherence in the game that reminds us of the spirit of people like Mario. The menu itself calls Major Keen: Goodbye, Galaxy, a game released almost two years earlier. Game development means the development of standards, and the characteristics of today’s quality of life are obvious. Not open – it’s possible if you play carefully – but enemies don’t play and if you’re not careful, you lose lives that are quite limited if you don’t have all your eyes open. It was published in freeware in 2005 and is available for download in 3D Realms and Good Old Games. The game is characterized by a complex and careful level design. A free software since 2005, Bio Threat is not sufficiently recognized as one of the best PC platforms of its time. The others are Solid Snake and. It is standard in its mechanics, with the ability to run, jump, shoot and throw grenades. Of course, Nautical is aware that the word “archaic” is in the eye of a very bad observer. I like all video games.
