Radiation Island

To draw comparisons with some other games on the app store Radiation Island (RI) combines the combat and world design of GTA: San Andreas and Dead Trigger with the crafting of Minecraft. You can build things and gather resources too but you are somewhat limited in the building aspect, nothing really lost there. Graphics are beyond any other game on the App Store. 100% worth the money and there are no in-app purchases or nagging ads. The rest of this review will be SPOILERS so if you haven't played, don't read any more.
The game is amazing but it would have been cool to see wolves you can tame instead of just kill but then again this is a world with zombies so maybe everything is insane or something. Not having an iron pickaxe is kind of strange too. At first I thought the transit location/teleporter was kind of cheating but I see why now. I just think maybe it would make more sense if you actually had to be at a transit location to teleport instead of just being anywhere (considering you can only teleport to transit locations). There is also a glitch in some parts of my game where you will fall through the sand and become trapped. The only way I got out was by teleporting so maybe I shouldn't complain about that. There are also only 4 guns in the game, I'm not finished but that seems about all there is in terms of firearms. It would be cool if there were just a few more guns. Maybe a shotgun, sniper rifle etc or hell, maybe a grenade or working artillery.

By far the best game I've ever played on iPad

Well, Lost is my favorite tv show of all time, and this game is basically Lost + zombies. I can't believe how cheap it is. I throw so much money at these BS games that just kill time -- I would be willing to spend a decent amount of money on an expansion or console version (although it’d essentially be Dead Island - I just really love this game.)

I was starting to think this game was getting repetitive until I prematurely tried to disarm the center island tesla, then I realized I should just go work on the third (NE in my case) island first. And HOLY MOLY the third island was like a whole new game entirely. So many more bases, a hidden little oasis through a tunnel of trees, with actual decorations in the houses that you can take. Crazy amounts of zombies, but crystal transformers at every transit location.

I love this game and cannot believe it isn't more popular.

Anyways -- the few cons I've noticed (that don't make the game unplayable at all) :

Zombies get stuck in walls, a lot of the dig sites don't work, sometimes auto aim doesn't seem to work but I suppose that could be user error, there could be different enemies or some more change of scenery.

Anyways -- spend the three dollars and try it out. It's a hidden gem of the App Store. I’d legit pay a good $30-40 or so on a PS4 version.

So I love this game it’s very fun and I spent hours on it. However, I had a glitch that restarted my entire island and all my progress. I learned that I need to constantly cloud save to ensure this doesn’t happen again. And I find that kind of annoying. Another thing is once I completed the first island, the game became a buggy mess. For starters gliders don’t work at all, I went to the top of a mountain and there was nothing in my path, it was destroyed. I wasn’t even close to the ground. Another thing that happened was my character would start jumping over and over again. The only way to stop that was to reset my game. Another bug was the game crashing every 5 minutes and NOT saving my progress. The final bug so far is clipping through the ground and I must die to get out if there are enemies nearby. So all in all, once you complete the first island (which I found really fun) there is not much after the game when you go to another island because it starts to become glitchy to the point it almost unplayable because important features don’t work. I would give it 5 stars but because it is a paid game and it gets really buggy, it will sadly only receive 3 stars if by any chance you are able to fix these (I do realize that this is many years after the release) I would love that and I would give it 5 stars.
