Digfender vs Plants vs Zombies
Digfender
Digfender is a fun and challenging tower-defense game that, unlike many other games, is set underground. In this game, your ultimate goal is to protect your castle while digging a way down towards a cavern (possibly containing treasure). However, as you dig, creatures that have slumbered in the frozen ground will be awakened and they aren't happy with the rude awakening.In terms of gameplay, this game is intriguing to say the least, because you not only get to dig the path in which your enemies will be using; you will also need to be strategic in the placements of your towers. Towers come in many different ranges and damage capacities, allowing you to mix and match them until you find the perfect combination. Of course, each tower can be further upgraded and augmented, via support towers, giving them high damage, longer range or even faster XP gain so you can level them up.
The different types of enemies, along with their unique set of strengths and weaknesses, also provide you with some extra challenge. What's most interesting, however, is the fact that you can replay a level to collect a special token called a Relic. Relic tokens can then be spent in the special upgrade tree in the game.
All in all, Digfender is a fantastic tower-defense game that is as fun as it is strategic. If you're a huge fan of tower defense games, this is a game you'll want to try!
Plants vs Zombies
Plants vs Zombies is a whimsical tower defense game that places you in a unique position, mainly by planting a wide variety of plants on your lawn, to counter the advancing horde of zombies that are about to invade your home. You'll gradually expand your troop of potted plants as you progress to increasingly challenging levels and you'll need to adapt to the game as its situation changes, such as defending against the horde on your roof or at night. The coins you've earned from playing levels can then be spent at Crazy Dave's shop which he ran from the back of his van. There's even a mini-game of sorts where you can plant and harvest a variety of items, including coins, in your own garden.Proclaimed as being one of the modern classic tower defense games, Plants vs Zombies (PvZ) set a high bar for other similar TD games to follow and from what we can see, only a handful (Kingdom Rush, for example) managed to make it to a similar level of popularity as PvZ has enjoyed. PopCap Games has even followed up PvZ's huge success with exciting sequels (only on mobile though) and equally-entertaining spin-offs, like the PvZ: Garden Warefare game which diversified the entire franchise by delving into the competitive shooter genre.
