Space Invaders Evolution

Space Invaders Evolution is a mobile variant of Taito's classic series of space shooters. Although it shares its name with the 2005 PSP game, it is more similar to Space Invaders Extreme. The basic concept behind the game is the same as before. The player controls his space ship in the bottom of the screen and has to shoot down all the alien invaders that appear above him. The shooting is automatic by default but this can be turned off at any time. The aliens come in different colours and by shooting down aliens of the same colour sequentially, the player can be awarded score bonuses. At times UFOs will appear at the top of the screen. By shooting these down they will drop their supplies which the player can pick up and use as power-ups. These include an extra life, and weapon upgrades such as bombs, broad shots, lasers, and E.M.P. blasts that destroys all invader shots and cause them to move and shoot more slowly.

The aliens come in a number of different flavours. Not only do they differ in colour but also in their weapon configuration. In their most basic form the invaders uses one of three weapon platforms although there is also upgraded variants of these. They are crab, squid and octopus. The crabs are standard invaders with simple projectiles. Squids uses high velocity plasma rays. They are much faster and harder to dodge than the crabs. The octopodes are slow and easy to dodge but use powerful bombs whose explosions can harm the player even if not hit directly. The invaders also have different characteristics depending on their colour. For example white ones both move and shoot slowly while the pink ones move faster and the yellow ones shoot faster. Most advanced are the black ones who both move and shoot at very high speeds.

The game has a number of different game modes. In addition to the standard mode where the player has to blast his way through wave after wave of better and better aliens, there is also different quick play modes available. These are: Hard Rain*: the player has to avoid the rain of enemy projectiles and shoot the hidden invaders that occasionally pop up before they reach the bottom

• Combo Run: the player has to maximise his score by chaining combos by hitting invaders of the same colour or shape

• Onslaught: the aliens throws everything they got at the player who has to take down as many of them as possible

• Master Says: the player has to hit the invader shown at the top of the screen before it reaches the border of the screen

• Boss Rush: the player has to beat all the bosses in the shortest time possible
