Bloons Tower Defense
BTD (Bloons Tower Defense) is a Tower defense game. The aim is to choose the right tower to hopefully win the map! Upon winning the map you get amounts monkey money depending on the difficulty that you played on. Monkey money is the general in-game cash for BTD and can buy you upgrades and special agents as well as other awesome stuff as well! During the rounds you're currency is banana's (Yeh, the game's centers around monkeys xD.)
BTD has about 20 towers to choose from each which you must upgrade. Once you unlock an upgrade it's unlocked permanently meaning that you don't have to unlock the same upgrades every round. Towers can only have six upgrades out of eight. You can either upgrade the first side to two and the last to four or vice versa . You don't have to do that, you could go 1:1 or 2:2 or any combination that's not 3:3, 3:4 or 4:4.
[size=12]Multiplayer is possible on BTD, basically on player controls the left and the other controls the right. Multiplayer isn't local as far as I'm aware. You can choose to play multiplayer with a friend via Facebook, or you could play with a randomly picked person. It's better to play with a friend in my opinion because you can speak to them over phone or something similar and discuss which towers to put where.[/size]
I think that BTD is definitely worth a play, I myself love it! It can be played online, on your PC or on your phone (excluding some phone :/ but IOS is a definite). Unfortunately you have to pay for it but if you type in on google BTD 5 for free iOS there's a video that shows you how to get the game for free. I'm not taking credit if your area doesn't support the video. My friend did this for me and it works fine, he originally told me he was gonna download BTD battles (the crap version) and did that Lol. Anyway, it's worth a try the current version is BTD 5. Enjoy it, and comment tips / tricks / favourite towers down below!
