Worms has been around for years and still has new releases, yet this game remains on top. There are two primary gameplay modes: Campaign and Deathmatch.
The campaign is comprised of different levels that teach you the gameplay mechanics and give you different goals to reach with a given set of weapons. It starts out explaining how aiming, power, and wind effect different weapon such as grenades and the bazooka. You quickly learn how different weapons react to different environments. The game then puts you in situations where you have to get from point A to point B while only using specific utilities. There are many levels that will only be completed through trial and error--and that is one of the best parts of the game--it doesn't hold your hand. You learn how everything works through experimentation. You learn for example, that a girder can be used for protection as well as to traverse the maps.
Death Match is a simple 1 on 1 where each player takes turns controlling an individual worm trying to eliminate the other team. It starts out simple, giving you the obvious advantage in team size and poor ai aiming, while slowing ramping up the difficulty with each match. By the end, you have a smaller team size and the ai has impeccable aim. The last match will likely take many tries. But, when you do win, you will feel like you truly earned it.
All Worms games follow the same mold, but what makes this one truly stand out is the customization. You choose the name of every worm on your team as well as their gravestone and voice from a huge list of options. When you want to face off with a friend or the ai, the game gives an astounding amount of options that are sadly lacking from more recent titles. You can choose which weapons and utilities you want available (there is a lot to choose from!), how much ammo they have, when they can be used, etc. You can choose how often health/weapons/utilities drop. You have control over worm life and sudden death options. You can essentially change anything you would possibly want. Don't like the random stages the game gives you? You can create your own stages as well!
One of the things that makes Worms Armageddon so great is that you can play multiplayer locally as well as online. Sure, you can see all of your opponent's crate pickups during local play, but nothing beats being able to see their face when you land that amazing grenade toss to win the game.
Although newer titles may look nicer in the graphics department, this game still reigns supreme in terms of content and customizability. This game was amazing in 1999, and it still holds up today in 2015.
