Nival’s take on the tower defence genre, Defenders, has just made the jump from PC to iOS.
Adding a collectible card game element to the standard tower defence gameplay, Defenders has you build and customise a selection of towers over 23 levels. You collect cards - and in turn towers - by completing levels. You can also choose to fuse cards you are not using, creating towers with new abilities.
All of the original PC game's visual and audio seems to be present in this port. This means on smaller screens that the combat can become quite busy. Luckily, a pinch of the screen will zoom you into the action to ensure that you aren't accidentally throwing up towers in the wrong places.
Placement is particularly important in Defenders, as certain areas of the map apply buffs to your structures. You'll need to level-up towers as you play, and master the use of area-effect spells, ensuring you will constantly micromanaging your army.
Defenders's additions to the formula make it a deeper alternative to the more causal tower defence games on the market. You can get it from the App Store now for £2.99 / $4.99.
