Specs
Pros
Pro Clean graphics
The gameplay in previous games (TD4 and lower) was a bit laggy at times, luckily TD5 has cleaned up the graphics to make them a bit more simple while also allowing for new designs that differentiate things in the game in order to make it easier to tell what is going on. The cleaned up graphics also allow for smother gameplay due to them using less resources, meaning no more laggy gameplay.
Cons
Con Microtransactions in the game
There are microtransaction in the browser game for things such as in-game currency, tower buffs and progression locked towers. While the game can be played completely free, it will be much easier to play if you are purchasing content that makes the game easier. Some may see this as pay to win.
