I purchased Star Defense back in July 09 and have only just managed to play it. With a barrage of games to play this was put on the back burner. After purchasing an IPAD I decided to give this a go on this device. I have been playing this on and off over the past few weeks and managed to complete the game whilst watching the world cup games
The objective of the game like any other strategy tower defense game is to defend your base from the incoming enemies this time being aliens. The hook of this game seems to be the planet being your level which is an ingenious piece of level design. You pinch, pan and zoom around the globes and add towers in key locations to defend your base. Enemies come in waves and in a variety of sizesthey are immune to certain types of weaponry i.e. fire, plasma. So you really need to have an assortment of cannons placed to maximise your chances of success.
A few strategy hints I could give is to make the most of your environments. You need to really use each tower/gunner in the optimal position i.e. covering the most area/radius possible. Also, it is better to upgrade your weaponry rather than adding towers. The plasma and flame cannons should be your staple and adding the slow down cannons at key locations such as opposite flame or plasma cannons can help but I wouldn’t use them more than two or three of them on each level. I completed the last level using only 20 out of 30 possible towers and the majority were upgraded to the max.
Lastability is around 8-10 hours. The fourth planet was really challenging and took the most effort. It is a very addictive game but there are gameplay balancing issues as mentioned before which hampers the experience a little bit they could learn a thing or two from Popcap. All in all I enjoyed this very much and similar to Plants vs Zombies has that ‘one more go’ appeal.
