fun for a minute
this game is really fun for a while then it gets repetitive. the music is a fun beat. the game IS extreme compared to the original version. the enemies come in different colors and sizes. and if you kill a chain of the same color you get a super weapon depending on the color you killed. fun game but wait till it gets to $10 range. if it ever becomes a $10 digital download then it's a must buy.

Surprising
I liked space invaders back in the day, but it does get rather repetitive after a while. Well this new version solves that problem. Yes, you still go back and forth on the bottom of the screen shooting at aliens, but now there are power ups, special weapons, lots of different aliens, boss battles, new attack formations, and even new powers for the aliens themselves. The colors are vibrant, and the game is strangely addicting. The constantly flashing back round might be problematic for anyone who is epileptic though, and I found no way to turn it off. That aside, this is a great retro game made new again.

Retro Fun!
Great addition for the PSP. Graphics are great and the fun factor is definetaly there. Great game to kill time, Highly recommended!

Oh My God, its the Invaders =)
Its one of those games that when you die you say "well let me play just one more game" and before you know it its time to get up and go to work.

Its not an "emulator", they actually re-made it, with colorful backgrounds, cool sound effects, and killer addiction.

Its simple and easy to pick up and play, perfect for casual gamers who just want to shoot aliens for a while. I love the upgrades of the weapons they did for the PSP, its VERY colorful, so your eyes might hurt if you play for too long. Its also very fast passed, so you will always be on your toes (or thumbs in this case).

Lots of fun, and everyone in your family can enjoy it.
A must have for "old school" lovers.

Earth is invaded... again!
After playing through the PSP demo many times over the past several months, I could not wait to get my hands on the full version of Space Invaders Extreme... I am not disappointed.

It's still the same old formula, you move your 'cannon' along the bottom of the screen and shoot moving 'invaders' as they inch closer and closer towards earth. This time though, there are a lot of variations in the mix. The invaders themselves come in several different sizes, extra small, small, regular, large and extra large. They are set up in various formations and have different flight patterns and attacks as well. Some invaders have shields, some have reflective shields that bounce your shots back at you, some even turn sideways and being two dimensional, they nearly disappear! There are also new type of UFOs, each with different colors and attacks.

Scoring is based on several factors. You can set up scoring combos with a 3 second timer. As long as you keep killing, the combo chain remains. You are also awarded bonus points for level-specific attacks, like shooting out each column or row at a time, killing all the same color or shape opponent in row, etc. Also, if you kill four of the same color enemies in a row, a timed weapon upgrade appears... this can be a laser, bomb, or spread shot. Complete the level-specific attacks to deploy a flashing UFO. Shoot him down and a minigame starts, maybe kill X amount of invaders in a certain timeframe, or kill just one well protected invader, etc.

Boss battles signal the end of a level. They are often very large invaders and have different critical kill spots.

One great addition to the classic gameplay is the ability to save and start at the beginning of the level when you load or continue a game. No more starting from scratch every time. Your score will also start at whatever it was at the beginning of the level, so you can rebuild on that.

A multiplayer mode is included via Ad-Hoc as well.

At $19.99, this title is a steal for fans of retro gaming, causal gamers (you only use one button after all), or hardcore gamers looking for a challenge as the levels become faster and the enemies come in thick waves.

My only knock is that some of the backgrounds are a bit 'Windows 95-y'... just boring, ugly text floating around. But you're usually too focused n the gameplay to notice.

A great overall budget game with strong mass appeal.

Thirty years old and the core gameplay still holds up!
