For 3 bucks this game is a steal, for the high quality of it's gameplay/design and quantity of content it's also one of the best games I've bought on the Mac App Store. The campagn consists of 20 levels with 4 modes of difficulty, so you'll need those upgrades, and has a ton of replay value not to mention the Classic mode (which is kind of like a challenge mode with set weapons and powers for different maps) and of course, Endless mode for all 16 maps. Though the Commader is provided to you from the start there are a TON of upgrades you can earn for him including weapons, new abilities, and his individual stats (health, weapons range, strength, firepower). The additions of a Commander (which makes you feel like much more a part of the action) and multiple gates to defend (which adds multiple levels of strategy to the game, with the new need of a possible fallback position) are what makes this game truely special. Sentinel 3 holds it's own with it's upgradable towers, unlockable weapons, and killer enemy waves not to mention it's amazing graphics, sound, and UI. IBomber is the standard for tower defense games, with it's WWII setting, and most TD games are basically a clone of this type of game except for rare exceptions like Sentinel 3.
In my opinion there are only 2 tower defense games that are absolutely essential on the Mac App Store, IBomber Defense & Sentinel 3.
