Wii Play/Tanks!

In this game, you are a blue (P1) or red (P2) tank. Your object is to destroy all the enemy tanks in each level. It has a play structure similar to Table Tennis. The first time through, the game consists of 20 levels, which must be beaten in succession. This earns the gold medal. Then it stops you, and then you have the chance to go through 100 levels.

Each tank destroyed is worth one point, and you receive one extra life for each five levels completed.

The tanks
You are one type of tank, and there are nine types of enemy tanks, followed by six extra types of enemy tanks, for a total of 16 types. Each one's capabilities are outlined below.

Conventions
The tanks are formed from combinations of attributes:
 * Bullets: slow/fast
 * Movement: none/slow/fast
 * Mines: none/one/multiple
 * Intelligence: varies

Player tank
P1 is blue, P2 is red. This tank moves at a medium speed. It can shoot five slow bullets at a time, which ricochet once. It can lay two mines at a time.

There are only two play modes, single-player and two-player.
 * Play Modes

In single-player mode, you must first beat missions 1-20, then start over and try to beat all the missions (there are 100 in total). Missions 1-10, after you become familiar with the game, are very easy and serve simply as a way to up your life count to 4 or 5. Of course, as you grow more and more experienced with the game, later missions while seem like this too. At mission 50, the black tanks are introduced. As they are one of the most difficult tanks in the game (in general), mission 50 is another turning point in the game. After that, you go on to 1,000 missions, meeting the six remaining enemy tanks. Another thing to keep in mind is that while there is a good number of new stages after mission 20, several of them are simply repeated with different enemy tanks. Mission 100 is a perfect example of this. The only major downfalls of this mode are the inability of the player to save their game and the unadjustable difficulty.
 * Single-Player

In this mode, two players can go up to mission 20 (but most unfortunately, no further) by working together. The number of enemy tanks or their position are sometimes different when compared to single-player mode, but overall the missions are very similar. Two-player tanks is insanely fun, but it has two major downfalls (in my opinion): Lack of missions beyond 20 and only one life per mission for each player (this was probably done to make 20 levels challenging enough to make up for the low quantity). If Tanks was to ever be made into a full-fledged game, as I hope it will be, the problems with the two play modes could easily be solved.
 * Two-Player

Enemy tanks
Although they all behave differently, they have a few common characteristics. For example, the tanks that move never stop moving. The moving tanks can push the fixed tanks around.

First, however, you have to know how to effectively ricochet your shots. The concept is simple, but can be difficult to properly make use of in the heat of battle. There are two main types of ricochet sequences: offensive (to destroy enemy tanks) and defensive (to keep away enemy tanks or shots; can easily turn into an offensive ricochet sequence). Each of these involves three main types: acute angle ricochets, obtuse angle ricochets, and right-angle ricochets. The first is when the angle the original path and ricocheted path of your shots is less than 90 degrees, the second involves angles greater than 90 degrees and less than 180, and the third angles equal to 90 degrees. Use each one in the appropriate situation.

These first appear in Level 1. They are fixed (non-moving), and can only fire one slow bullet at a time. They do not lay mines. Their turrets do not actively seek the player, but only search randomly, firing if you cross their path. Very easy to defeat. A direct shot will finish one of these off.
 * Brown (Turret)

These first appear in Level 2. They move at a slow speed, and can only fire one slow bullet at a time. They do not lay mines. Their turrets mildly seek the player, but their movement does not. They are neither offensive or defensive in their movements. A quick burst across their path will usually destroy them.
 * Gray (Soldier)

These first appear in Level 5. They move at a slow speed, and can fire one fast bullet at a time. It does not ricochet. They do not lay mines. Their turrets strongly seek the player, but their movement does not. They are defensive in their movement, and avoid bullets and mines. Avoiding direct engagement is desirable, so stay under cover and use ricochet shots to destroy them. Two things to keep in mind when facing these tanks are the 'continuous movement strategy' and the 'point-blank zone'. The continuous movement strategy is simple: keep moving in one direction while shooting at these tanks if they can shoot at you. In other words, if you are in a direct-confrontation situation, use this strategy to make their shots miss. Why does it work? Because almost all the time, the dark green tanks' shots will seek the current location of a player; they won't aim for where you will be. This, however, is where the point-blank zone comes in. If you are close enough to the dark green tanks, their shots will simply be too fast to effectively dodge. You will need to use shot deflection to protect your tank. This is true for any tank, of course, but even more so for the ones that fire the fastest shots (dark green, light green, and black).
 * Dark Green (Hunter)

These first appear in Level 8. They move at a fast speed, and can fire one slow bullet at a time. They lay multiple mines at a time. Their turrets mildly seek the player, but their movement does not. They are neither offensive nor defensive in their movements, but strongly avoid mines. Getting in close and firing a burst deals with these relatively quickly. It is important to note that sometimes these tanks will go suicidal. They often move into your line of fire if it wasn't already headed for them. The problem comes when, by doing this, the yellow tanks lure the player into a trap. This usually involves mines that are invisible due to walls blocking it from your view, but can involve a different yellow (which can be very aggressive) attacking from another side. Although these tanks, by themselves, are not very dangerous, they can easily become so when they have stronger tanks to back them up because of the sheer number of mines they put down and their random aggressiveness.
 * Yellow (Bumblebee)

These first appear in Level 10. They move at a slow speed, and can fire multiple slow bullets at a time. They do not lay mines. Their turrets and movements both seek the player. They are offensive in their movements, and avoid bullets and mines. When facing these, always keep moving or you will be destroyed! Shoot at them, but do not pause for long. Move closer and closer and eventually you should win because of your greater firepower. It is essential to master battle against red tanks if you want to even stand a chance against the purple ones.
 * Red (Rover)

These first appear in Level 12. They do not move, and can fire one or two fast bullets at a time. These bullets ricochet twice or three times in level 17. They do not lay mines. Their turrets strongly seek the player, and they calculate the ricochets with considerable accuracy. The most difficult threat they pose is when two or more fire at you simultaneously, but from different angles. It takes a lot of practice to overcome this, but always try to minimize the time in which you are in a situation where this would be especially dangerous.
 * Light Green (Sniper)

These first appear in Level 15, where they are arguably at their most difficult to defeat. They move at a fast speed, and can fire multiple slow bullets at a time. They can lay one mine. Their turrets and movements seek the player, though not as strong as some. They are only offensive if a line-of-sight to the player is present. They are like red tanks, but more intelligent and faster. The strategy they use most is the 'ricochet and attack' one (where they send ricochet shots near you, then move in to attack, effectively increasing the chance of a shot hitting you). If you can defend against this and then skillfully go on the offensive when they are vulnerable, they will become much easier to defeat. They have a tendency to coordinate movements with other Purple tanks, and this makes their 'ricochet and attack' strategy a far more deadly occurrence. Just remember to never think it will be an easy win and wait for opportunities to pick them off one-by-one. As soon as the first one is destroyed, the next will be far easier than the last. And as with all difficult tanks, never become careless when you have a surefire chance to destroy them, as it can easily cost you a life or the game.
 * Purple (Warrior)

These first appear in Level 20. They become invisible after the level starts. They can fire multiple slow bullets at a time. They also lay mines. You can see them by the tank tracks they make when they move around by using an ID. It is crucial that you know how many whites there are at the beginning of the mission and during it. Under- or over- estimating will only hinder you. Try to figure out if white tanks are acting offensively or defensively at all times.
 * White (Stealth-Mech)

These first appear in Level 50, after completing Level 20 once. They have a very fast speed, the ability to lay mines and they can fire rapidly with the same missiles as the dark green ones. The battlefield of Level 50 is exactly the same as the one in Level 5, except the top one is facing horizontally. Unlike dark greens, their shots more often aim for where you will be, so if you are to stand any chance against them whatsoever, you must master the tactics of offensive and defensive ricochets, shot deflection, using mines, and basic trapping strategy at least.
 * Black (Elite)

These first appear in Level 110, after completing Level 100 once. They have a faster still speed, the ability to lay multiple mines and can shoot eight slow bullets at a time. They can be very defensive of their movements which makes them harder to hit and will only act on the defensive if they can kil you using their rapid fire. The best strategy against them is to fight first, using bank shots.
 * Orange (Streaker)

These first appear in Level 130. They have a very fast speed, can become invisible after the level starts, and fire as rapidy as the orange tanks. They are very good at dodging bank shots and will dodge nearly every shot in every way they can. The best thing to do would be to corner them using the trap defense strategy (That is, if they don't get away and you can even follow their tank tracks, which are harder to follow than white.)
 * Turquoise (Super Stealth-Mech)

These first appear in Level 200. They move slightly slower than the orange and turquoise tanks, but slightly faster than black. Unlike the other enemies, however, you will have to hit them 10 times with your bullets (Mines won't work, they are the best at avoiding mines.). The firsr phas is simple, you have to hit him five times. After that, the giant tanks activate shields. Now, you can only fire bank shots at them. They will also rapidly fire with the same missiles as the light green tanks to try and kill you more easily. After five bank shot hits, he'll go down and you'll be victorious.
 * Giant tank (Monster)

These first appear in Level 500. They have exactly the same phase as the giant tanks, except they become invisible after the level starts. Just follow their tank tracks, keep firing at them, doing bank shots at them after a while and eventually they'll go down as well.
 * Invisible giant tank (Stealth-Monster)

These first appear in Level 600. They move at a slow speed, but are the best at dodging bullets. They fire one bullet at a time, and do not lay mines. Old timer tanks are better at dodging bullets and mines than the other enemies, but are still easy to defeat because of their lack of speed and slow shooting. Pretty much the easiest of the six tanks after black to defeat.
 * Old timer tank (Grandpa)

These first appear in Level 750. They do not move, unlike the other enemies after black. However, they fire giant balls made of fire that ricochet ten times. When the fireballs hit a tank or a mine, they will cause bigger explosions, possibly killing you if you are close enough. You might have to fire very quickly and move the hell away again to survive, otherwise you're dead if they attack.
 * Skeleton tank (Destroyer)
