Worms: Open Warfare is an artillery strategy game.[2] It was developed by Team17 and published by THQ for the PlayStation Portable and Nintendo DS.[1] There are several other Worms video games in the Worms series. The game marked Team17's return to its 2D roots.[2] The game spawned a sequel, Worms: Open Warfare 2, which is also available on Nintendo DS and PlayStation Portable. In Worms: Open Warfare, the player takes control of an army of worms. The goal of the game is to defeat the opposing army through reducing the health points of enemy worms using various types of weaponry while avoiding friendly fire and other obstacles. The weapons and gadgets you use in battle include grenades, homing missiles, bazookas, cluster bombs, banana bombs (a Worms staple), dynamite, air strikes, shotguns, and many more. You can also choose from a variety of settings to battle in and make your own schemes and teams. The game is played in rounds with each worm starting with 100 hit points. Each team takes turns controlling one of their worms. The player is usually allocated 60 seconds per turn to move their worm around the battlefield and attack the opponent worms, though this time limit is customisable when playing non-career games. Only one attack is allowed per turn. In addition to timing individual player turns, each round has a 20-minute time limit. If the round timer runs down to 0:00 before a team claims victory, every worm's HP drops to 1, creating a sudden death scenario. During the course of a round, crates containing health or weapons will occasionally drop and the water level will rise.

Worms is a turn-based strategy game that combines tactical decision-making with elements of randomness. Players control teams of worms and take turns using a wide range of weapons and tools to defeat opposing teams, resulting in varied gameplay outcomes. The game offers numerous possible strategies and scenarios, contributing to high replayability. While the basic mechanics are simple, players may require some time to become familiar with controls, weapons, and tactics. Worms supports both single-player and multiplayer modes. Team17 planned on producing Worms for the Virtual Boy back in 1995. Though after a few weeks, they cancelled this plan due to the lack of interest of the publisher and the expected failure of the Virtual Boy.

Shining Force is a turn-based tactical RPG. Battles take place in square grids, and each unit occupies 1 square. Units can belong to one of two sides: allies (controlled by the player) or enemies (controlled by the computer AI). Each unit can move up to a fixed amount of squares along the battlefield, determined by its Move statistic. Depending on its location relative to enemies and to allies, a unit also has the option to attack, cast a spell, use an item, search (if adjacent to a treasure chest), or stay and do nothing, all of which end the unit's turn. Some commands, such as equipping or dropping items, don't count as actions, and the character's turn is able to continue. The order of the turns is determined by the unit's agility score and a random seed. Units can use offensive actions, such as physical attacks or offensive magic, only on units belonging to the other side and can use supportive actions, such as healing magic, stat-enhancing magic, and items, only on units belonging to the same side.

Just because this battle fits in the palm of your hand doesn't mean the stakes are small. On the contrary, this all-or-nothing fight will have you accessing guns, grenades, launchers, and weaponry of all sorts. Players assume command of an army that's out to reclaim a world that's been broken up by warring factions. The battle map is essentially a grid, and moving units is like moving chess pieces on a board -- each of the units can move a specific amount of spaces within this grid, and can only attack at a certain distance from specific enemies. Advance Wars features more than 115 maps, a map editor, head-to-head play via link cable, and an easy-to-understand tutorial mode for beginners.

Metal Gear Solid: Peace Walker is an action-adventure stealth video game and is the third action-based Metal Gear title made specifically for the PSP. The gameplay consists of two primary modes: Mission and Mother Base. Mission are the actual action sequences of the game where the player must infiltrate an enemy territory or fight a boss, whereas Mother Base is an army management. Some changes have been made to the standard Metal Gear formula: the player is now unable to move or shoot while laying down and while pinned to a wall, making Peace Walker the first game since Metal Gear to lack any crawling ability.
