Levels. Levels, levels, levels. If you liked
Lemmings way back when, but you wanted more levels,
Lemmings for the PSP has the answer. Not only does
Lemmings have all of the original levels along with a ton of new levels, but it also features a level editor to allow you to create your own levels using the different environments in the game. You can save these custom levels to your memory stick and even upload them so that other people can download them and try them out.
For those who aren't familiar with Lemmings, I should back up a bit. The idea is fairly simple. You are looking after a large group of somewhat dim-witted and accident prone creatures called "Lemmings". Basically, these little guys are content to continue in a direction until they get to an obstacle they can't pass and then they'll turn around and go the other way. They don't bother to stop when they reach the end of a ledge or when they approach a device that just shredded 30 of their friends ahead of them. So, in order to save them, you need to help them avoid such pitfalls and help them to safely reach the exit door. The trick is - you can't actually do anything directly to help them; all you can do is help them help themselves. Each level has a certain allotment of different skills, such as the ability to bash through solid rock, dig down through the dirt, act as traffic cops to prevent the others from reaching a pitfall, that sort of thing. To empower a Lemming with one of these skills, you navigate to that skill with the shoulder buttons, then use the analog stick to target the Lemming of choice and push X to empower him. In this manner, you can create Climbers, Floaters, Bombers, Blockers, Builders, Bashers, Miners and Diggers. Most of these names are fairly self-descriptive, but when you designate a Lemming as a Bomber, you are giving him a death sentence. He will count down and then blow into tiny pieces. This is typically done to remove a Blocker, who would otherwise keep blocking things up even after you've used other Lemmings to prepare the path for the others. Floaters have umbrellas and can drop from any height without dying -- they simply use the umbrella as a parachute if the height is too high. Some of the skills can be combined on the same Lemming. For example, you can make a Lemming into a Climber and then also make him into a Floater. Doing this will create a Lemming that has both the hat that indicates Climbers and the Umbrella that Floaters have. What's more, he can scale up to great heights and then float down from them unscathed.
