Before you purchase Metal Slug 3, you need to ask yourself how much you value ten dollars. This is a short experience that, even with a few playthroughs, won't last you long. The exclusion of the two bonus modes from the original Xbox version is certainly a bummer and would have added a few more hours of playtime. Metal Slug 3 is a lot of fun, but this should be a $5 download. Especially when original, awesome-looking shooters such as Omega Five are storming Xbox Marketplace.
