Bubble Tanks is a series of online Flash games by Hero Interactive. In it, you use a tank made up of bubbles, while shooting enemies and collecting their bubbles they explode into when defeated. The more bubbles you collect, the bigger and stronger your tank becomes.Bubble Tanks 1 and 2 have you controlling a Bubble Tank. There's also Bubble TanksTower Defence 1 and 2, which are Exactly What It Says on the Tin, and Bubble Tanks Arena, which allows you to build your own tanks, both your own and enemies'. Bubble Tanks 3, has the classic gameplay of the original two games plus the features from Bubble Tanks Arena.
Bubble Tanks 1, 2, and 3 provide examples of:
Anti-Frustration Feature: In Bubble Tanks 2, if you get damaged too much in an area and hence lose a lot of experience points, the next new area you move into will have quite a high chance of containing harmless Pinata Enemies.
Evolving Attack: Your Bubble Tank evolves to the next level once it collects a certain amount of bubbles. So do its attacks.
Although with 3, the system was altered slightly. Now, as the base size of the bubble increases, the number of usable (and more powerful guns) will increase respectively. Of course, achieving the next level will still increase the number of max GP (Gun Points) available - but the increase will be relative to the base size.
With 3, you can follow the evolutionary paths provided, use one of the player-made tanks, or just customize and create your own. Though, the number of guns you can use will be limited according to the base tank size.
Experience Points: When you defeat an enemy, the bubbles they are made out of get dispersed. By going near the bubbles or beating all the enemies in an area, you will collect them and your tank will grow. Collect enough and you will be able to advance to a stronger evolution path. Careful though- if you get hit by an enemy, you lose experience bubbles!
Frickin' Laser Beams: Averted with the Beam Cannon in Bubble Tanks 3. The attack is an instant hitscan move.
Game Over: Averted. If you get damaged at level one ad you have zero experience bubbles, you will get sent to the safest adjacent area. In short, you can't die.
Gatling Good: One of the weapons added to the first parts pack is a minigun.
Giant Mook: Several of them. Four of them serve as Bosses- The Spawn Carrier, Tri-Guardian, BFT and Destroyer.
GlassNinja: The Ghost Sniper. Least amount of health of all the final evolutions, but it can move extremely fast, become intangible, and the sniper move it uses hurts like a ton of bricks, does massive splash damage, AND pierces everything it hits.
The Goomba: All the enemy varieties you fight near your starting point are these- they cannot harm you in any way. You also tend to fight them in almost every bubble too.
Interface Screw: Sticky Bullets make your tank slow, Jammer Bullets prevent you from firing, and Ink Bullets cover the screen in huge ink blotches that obscure everything. Thankfully, all three are temporary, but still irritating nonetheless.
Instant Death Radius: Death Field Tanks. Not exactly instant death, but they drain your bubble count rapidly if you so long as to touch their red radius.
Level Drain: If you get hit by an enemy, you lose experience points! Thankfully, should you lose too many in a bubble, the next bubble will have harmless Pinata Enemies.
The Minion Master: The BFT Carrier can send out small, fast, invincible minions to shoot his enemies apart to shreds.
Monster Compendium: Present in 2. Note that one of the enemies (Sapper Fighter) was never obtainable due to a bug in the game that didn't allow the player to encounter it.
Mook Maker: Heavy Heavy Heavy 2, Spawn Tanks, Spawn Carriers, BFT and Destroyers are able to produce smaller Mooks. Especially notable is the Destroyer, which produces powerful Mooks as opposed to the rest which produce rather weak ones.
Power-Up Magnet: You attract experience bubbles as you pass near them. If you defeat all enemies in an area, you collect all the remaining experience bubbles regardless of distance.
Smart Bomb: 3 has the Apocalypse Cannon, which nukes and kills every enemy in the bubble. However, it takes a mind-blowingly long time to recharge, and there are Mooks with a special device that can neutralize the attack.
Shows Damage: Enemies visibly lose bubbles as they take more damage. Some of them lose weapons as they take damage (as their weapons are made of bubbles too).
Spread Shot: The 3-way spread, the 5-way spread, and the Sticky burst are a regular burst, and the Starburst Cannon is an exploding shot.
Unstable Equilibrium: Getting hit makes you lose experience, which weakens your tank, which makes it harder to kill enemies, which makes you more likely to get hit. Have fun Level Grinding!
Thankfully, the second game does give an Anti-Frustration Feature- if you get hit too often in a bubble, the next unexplored bubble that you go into will have a high chance of containing Pinata enemies.
The Virus: The Doomsday Infector, which sends a homing virus to infect enemies and slowly kill them. Once the infected enemy dies, 1-3 (2 in Bubble Tanks 3) new viruses will emerge, hell-bent on infecting more enemies.
All Your Powers Combined: You can merge 4 towers together to form a Mega Tower, which uses the attacks of the towers it was made up of, except souped up. And then there are Mega Mega towers, which are made of 4 Mega Towers.
Anti-Air: Present in this game as "Anti-Ghost" and "Ghost Splash".
Asteroids Monster: Splitting creeps. Cursed Creeps will become a ghost when they die.
Standard Status Effects: Slow (which slows enemies), Poison (which makes an enemy continuously lose health), Confused (makes an enemy move randomly), Weak (enemy takes more damage). Your towers can also get disabled by EMP creeps, which makes them useless for a short while.
