I don't think I've ever played a game more irreverent and wacky in its humor and design while also keeping to one of the most accurate and precise physics engines I've seen in a while.
Worms Reloaded is actually an updated rerelease of Worms 2: Armageddon (Do not confuse this with Worms: Armageddon. They're actually two totally different games)
released in 2009 and while it's one of the older titles in the Worms franchise, it is definintely the one with the most features, gameplay modes, options, and overall fun out of the games I've played.
Up to four teams each control a squad of four worms with customizable names, voices, and hats (in fact the Steam version has TF2-themed hats just for this occasion) and an arsenal of weapons ranging from rocket launchers, grenades, flamethrowers, and air strikes to ninja ropes, teleporters, and magnets to a variety of exploding wildlife and grandmas to the mighty meteorific field-wide death of Armageddon. These worms will use said weapons to blow the living hell out of each other in a manner befitting old-school Looney Toons designed by Michael Bay. Each worm only has a finite amount of time to make a move, inch across the battlefield, use whatever weapon or item they wish and end their turn. A surprsing amount of things can get done during this time, but moves must be planned very carefully as just about any situation can be used against you somehow if your opponent is creative enough.
The controls on the weapons are all fairly simplistic but at the same time surprisingly complicated. The physics engine is very in depth taking into account, angle, power put behind the shot or throw, wind power and direction, and the presence of any obstacles. The precision in which things can be done is fairly impressive and a competent player can do things that might not even seem possible. It is worthy to note while keyboard controls are present, a controller is generally recommended for this game due to how strange buttons are mapped originally, but this can be changed. Gravity effects everything BUT the terrain you're standing on. The randomly generated maps and backgrounds will stay put no matter how many pieces are blown apart until you're either sitting in a crater, traverssing tunnels, or recreating Bastion. However, even a remaining pixel can be the difference between a hit or a miss in some cases so keeping track of what was destroyed how can sometimes work to your advantage but freak accidents can always happen.
One thing that's consistent throughout any worms game, especially in multiplayer, is that no matter how good one side is compared to the other, random chain reactions and other assorted problems can show up as a result of anything happening. A grenade could be thrown and throw an enemy worm into a mine, which detonates a nearby gas canister that lights an area on fire that eats through the ground and frees up a hole for someone else to fall into- right onto a health crate that fell down previously. But by no means is this a luck-based game. Freak happenings aside, the mechanics, complex physics, and sheer creativity allowed in the vast arsenal of weapons and tools requires quick reflexes, careful planning, and a good knowledge of how the game works and mastering these can take quite a bit of practice.
While this game is best played with friends, the single-player campaign is long and full of missions ranging from puzzles to challenges, to simply difficult missions and the AI at later levels is surprsingly advanced given how complex the rest of the game is. Unfortunately, the campaign isn't really worth playing more than once as each mission has a special 'trick' to it that can render it fairly easy in the hands of a skilled player. The actual multiplayer is where most of the action is. Randomly generated landscapes of a variety of colors, themes and backgrounds from ancient Egypt to Hell to outer space never makes for the same game twice and customizable maps and game modes allow for more exacting factors to be controlled ahead of time should you wish it. Due to the antics of how the game works, I recommend you play with actual friends either in person (It's worth noting that local multiplayer only needs a single controller) or online, but online multiplayer is also a perfectly viable option. Fair warning to those who care, however: There is no word censor in this game and enemy team or word names you come across online can be inappropriate.
Overall this is a fantastic multiplayer game that, if plugged into a large monitor, projector, or TV can make a fantastic couch party game that doesn't rely heavily on the RNG, but has just enough chance to allow laughs at a chain of explosions due to a misplaced land mine. There's enough customization to keep games from getting boring or samey and custom teams are always fun to deal with and it's very easy to personify the little guys and give each of your team a distinct personality or strategy type in your head. The single-player allows for a lot of time invested and makes for good practice and a rewarding experience by itself. Still, only get this game if you plan on playing it with friends.
