Bank Panic

In the world of retro gaming, there are countless gems that have been long forgotten, buried among the more popular titles of their time. One such gem is the SEGA Master System game, Bank Panic, released in 1986. This little-known game packs a punch with its simple yet addictive gameplay, and is a must-try for any gaming enthusiast. Released by SEGA, Bank Panic is a western-themed shooting game that was originally an arcade game but was later ported to the Master System. The objective of the game is to protect a bank from being robbed by a group of bandits. The player takes on the role of a sheriff, armed with a revolver and his trusty reactions, trying to defeat the bandits before they can take any of the gold stored in the bank's vault. The gameplay is straightforward and easy to grasp, yet challenging enough to keep players engaged. The player must aim their revolver at the bandits as they appear in different windows of the bank. Shooting the bandits at the right time and in the correct window will earn the player points, while shooting innocent passersby will result in losing points. The game has a dynamic difficulty curve, with the bandits becoming faster and trickier to shoot as the levels progress. One unique feature of Bank Panic is the addition of special bonus rounds every few levels. These rounds offer a welcome break from the intense shooting gameplay and add a fun element to the game. In these rounds, the player must shoot flying bags of money for added points. However, this also poses a challenge as the bags move quickly across the screen. The game's graphics may seem simple and basic by today's standards, but for its time, they were considered groundbreaking. The animated sprites and smooth scrolling backgrounds were quite impressive for a console released in 1986. The game also features a catchy soundtrack, adding to the overall experience. Bank Panic's high replay value is worth mentioning. With its challenging gameplay and three difficulty levels, players can continue to test their skills even after completing the game. Moreover, there is also a two-player mode, allowing friends or family members to compete against each other and see who has the fastest reflexes. Despite its limited popularity, Bank Panic undoubtedly helped pave the way for future shooting games. It may not have achieved the same success as other SEGA titles, but for those who have played it, Bank Panic holds a special place in their hearts as a hidden gem of the Master System library. With its addictive gameplay, simple yet effective graphics, and high replay value, this game is a classic that should not be forgotten in the world of retro gaming.

Bomber Raid

Fly your plane through five levels, shooting enemy planes, submarines, helicopters and other enemies along the way, and use your equipped cluster bombs if necessary. You have to destroy a target indicated in the mission briefing. You have three lives and a limited number of cluster bombs. To help you along the way, you can fire an energy capsule to earn points, increase your firepower and get help from other squads.

Fantasy Zone

Fantasy Zone for the Game Gear landed in 1991 as a curious bridge between arcade flamboyance and handheld calcified simplicity. Sega took the neon whimsy of the original coin op and adapted it to a tiny black monocle screen that begged for a patient finger on a D pad. The result felt like a carnival ride that had learned to fit into a pocket. Players piloted Opa Opa, a plucky propulsion ship, through dreamlike landscapes stitched from bubbly colors and improbable architecture. The handheld version preserved the saucy humor and bright palette, even while squeezing performance into modest hardware limits. Once in motion, the ship hovers with a jaunty tilt as enemies swirl in cartoonish formations and the world scrolls at a gentle clip. The charm lies in its shop mechanic: you earn coins by blasting oddballs and rescuing koi-like creatures, then pause at a magical storefront to upgrade engines, firepower, and shields. The Game Gear edition preserves this loop, though the hardware nudges you toward shorter routes and snappier bursts. Boss encounters punctuate zones with oversized silhouettes and punishing patterns, inviting a patient reader to study timing and angle rather than brute reflex. The music blooms with brass cheer. Visuals in the portable edition shimmer with a celebratory garishness that fans remember from coin op days, yet they adapt to a grayscale friendly palette on the small screen. The sprites breathe whimsy, from fat balloon enemies to smiling cannons, while parallax scrolling breathes depth into a corridor of emeralds and pink sunsets. Its control is crisp, with diagonals allowing Opa Opa to weave between hazards without losing momentum. Sound follows a similar cheeky cadence: short bleeps, jangling melodies, and a triumphant chime when a zone folds shut after a final strike. While not exact, the spirit remains irresistibly kinetic. Fantasy Zone on Game Gear stands as a curious relic that nonetheless earns praise for ingenuity. It captures a signposted whimsy and converts it into bite sized sessions that suit quick commutes, long waits, or lazy afternoons. The upgrade loop remains the beating heart, inviting experimentation rather than grinding, and that invitation translates well to curious newcomers sieved through retro curiosity. Though the screen can feel cramped and enemies cluster densely, the game rewards experimentation with unexpected pathways and quirky shortcuts. For collectors, the cartridge is a reminder that handhelds once flirted with arcade opulence and won affection anyway.

Golfamania

Golfamania is a golf simulation game in which players play on an 18-hole course with all the rules and scoring as in the real game. Within the game there are 4 different modes to play which include Practice, Match Play, Stroke Play and Professional Tournament. In Practice mode, a single player can play any of the 18 holes available. Match Play is the 2-player mode against a human or computer. Stroke Play is the mode in which the player can play with up to 4 people, including a computer player. In this mode the character's skill can be increased in 3 different areas which are power, accuracy and luck with the 6 different characters available. The main mode is the Professional Tournament, in which the player faces more than 30 computer players (all playing on different holes) with the goal of getting a lower score than the other players (according to the rules of golf). Depending on the performance, the player can earn experience points (XP) that can be used to improve the character's power, accuracy and luck for future tournaments. Some of the holes have prizes such as 'longest drive' and 'hole-in-one' that can earn extra XP. Regardless of the mode, the game plays the same way. The player selects a character (the selection depends on the mode) and then sets it up by giving it a name and choosing its style. In all modes except Practice, the player must choose 3 golf clubs to draw from his selection of 17 different clubs (wood 1-5, iron 1-9, pitching wedge, sand wedge and putter). When playing the player is presented with a top-down view where the player aligns the shot and location on the golf ball they want to hit (for spin). Next, the player selects the club they wish to use (they all go at different distances). Once this is done, the player must play the skill portion of the game, where they are presented with a power bar that has a marker going up and down along it. The player must stop the marker in the red area in the center of the power bar to get a good shot (the center being a perfect shot) and if missed in this area the ball will only travel about 20 yards (compared to over 100 yards for a good shot). The amount of red on the power bar depends on the club used. To help the player, the distance of the stroke can be reduced in exchange for lower marker speed and can be used for shots closer to the hole (very useful for putter shots). The game uses a RAM memory backed by the battery to continue the game later.

James "Buster" Douglas Knockout Boxing

James 'Buster' Douglas Knockout Boxing is a boxing simulator starring the former world heavyweight champion (replaced by the fictional S. Davis in the European version). The game should not be confused with the Genesis title of the same name, which is a completely different game. Instead, this title is completely identical to the Game Gear and Master System versions of George Foreman's KO Boxing, which served as the basis, only with George Foreman instead of James Douglas and reworked by Sims Co., Ltd, a subsidiary of the original Sanritsu team. The player steps into the shoes of James Douglas to contest a series of boxing matches against different opponents to win the championship title belt. The boxers are shown sideways. Players can move left or right in the ring to avoid punches. Other moves include blocks and left and right jabs, which can be varied into jabs and crosses. Fights can last up to ten rounds and, when a regular or technical knock-out does not occur, the winner is based on jury points, provided between rounds. During knock-out phases, no buttons need to be pressed to bring the boxer back to his feet. At the beginning of the game, a slow or fast speed can be selected for the game. In each bout, the player's boxer can use three super punches. They must be charged and triggered when approaching an opponent. It sends them straight to the back of the ring, a dangerous area as it is easy to keep hitting the ropes. Health recovers slightly during the intermission and after each match won the player receives skill points which are distributed into three traits. Two-player matches are supported.

Line of Fire

A man named Jack infiltrates an enemy base and discovers a secret weapon. He is soon pursued by disgruntled enemy soldiers who want their toy back. The game takes players through six levels controlling Jack in an armored jeep. Gameplay is shown through a top-down perspective, with the screen scrolling vertically at a steady pace. The jeep cannot access the top of the screen, only two-thirds of the screen, and getting stuck behind certain objects causes the jeep to explode. The jeep is equipped with an unlimited amount of bullets and about 50 missiles per mission. Certain objects in the air can only be eliminated with missiles. After launching them, players can apply 'aftertouch' to guide them to the target by moving left or right. The scenarios, which include a factory and a jungle, sometimes have obstacles, and also require the jeep to jump over rivers. There are three difficulty levels, the vehicle can take multiple hits, and there are three lives to follow.

Mahjong Sengoku Jidai

Mahjong Sengoku Jidai, released in 1987 by SEGA Master System, is a captivating game that combines strategic gameplay with the traditional tile-based game of Mahjong. Set in feudal Japan, this game takes players on a journey through the turbulent Sengoku period, where Warlords were constantly vying for power and dominance. The game features eight different Warlords, each with their own unique abilities and playing style. As the player, you must choose a Warlord to represent and lead through the game. Each Warlord has a specific starting location on the game board, which adds an element of strategy as players must decide which Warlord to play as depending on the tiles available on the board. The game board is a beautiful representation of feudal Japan, with vibrant colors and detailed artwork. The tiles themselves are intricately designed, featuring symbols and characters from Japanese mythology and history. This attention to detail adds to the immersive experience of the game, drawing players into the world of Sengoku Japan. The gameplay of Mahjong Sengoku Jidai is both challenging and addictive. Players must strategize and use their Warlord's abilities to defeat their opponents and gain dominance over the game board. The goal is to be the first player to collect four sets and a pair of tiles, called a "Mahjong," and declare victory. But beware, your opponents will be doing everything in their power to prevent you from achieving this goal. To add to the excitement, the game also features special tiles such as "Joker" tiles, which can be used to represent any other tile in the game, and "Bomb" tiles, which can be used to destroy an opponent's tiles. These special tiles can be the key to achieving victory but must be used carefully and strategically. Mahjong Sengoku Jidai also offers a multiplayer mode, allowing players to challenge their friends in intense battles of wit and strategy. The competitive nature of this mode adds a new level of excitement to the game, as players strive to outmaneuver and defeat their opponents.
