4.3/5 (66 votes)

In Bug Tunnel Defense, bugs are in fact our deadly enemies after an atomic war has laid waste to the rest of civilization, and they're coming for what is left of humanity. So, not much different from the present day, really, minus the radiation and the end of civilization. With 5 levels of tutorials and 40 levels of gameplay, Bug Tunnel Defense is short but entertaining. If you enjoy tower defense games, then try out Bug Tunnel Defense with its fun new twist on an old classic. And for heaven's sake, get those darn bugs before they wipe us all out.

It seems like the upgrade costs are bugged. For example, on the sear tower, I pay 50 gold on a tower with 10 damage (5:1 gold to damage ratio). The level one upgrade costs 100 gold for 10 extra damage (10:1 gtd, twice as much as the initial cost). I think that it should've been a 100 gold overall cost, making it just a 50 gold upgrade (back down to a 5:1 ratio).

In other words, until it gets fixed, just spam level zero towers. There's little point in upgrading towers now.

Can't seem to figure out how to get any of the "aphid" or "armor" achievements. They don't seem to work when I have them applied.

To obtain the aphid awards you need to be playing a level with aphids, so any level from the eighth onwards ("Frame") should do. The armor awards weren't being awarded on early levels, but the game has just been updated so it should work now.


One of the better tower defense games that I've played lately. I disagree with the review saying it's "short". This is one of the more time-consuming TD games out there.

All I can say is that this is the hardest defence game I've ever come across....

Maybe I'm missing something obvious, but by the time I start to think "oh, I've got this level worked out now", I usually die 15 seconds later!

I've gotten as far as level 9 - but by the time I use enough Sparks and Spikes to direct my traffic (because they're the cheapest), I'm broke, and death is imminent.

And why can I only use Stone after several minutes of play? If I have the chance, this happens just before I die as well....

So, I'm addicted now!

Nope, not a short game, but it's meaty.

If it helps, Guthlaf, I try to run the two streams together sometimes, and turn the paths back on themselves, to make guns go further.

Great game!

Thanks, Houseworkisevil (!) - I've tried, and I don't know if I'm just not upgrading enough before I meet my buggy doom, or...?

I'm stuck on the "Cheverons" level - it looks like level 9 to me, even if the computer says Level 6 (?).

How often have I died? I'm not sure - but at least ten. :-(


Oh... there are upgrades....

Well now I feel like an idiot! :-)


OK I was surprised by the "upgrades between levels" - the upgrades within each level are obvious (and standard). Upgrading between levels? Not something I expected....


OK, the between-level upgrades got me through 'Cheverons', but I confess, 'Scrolls' has me beaten. I surrender....


It's a fun game, but there is one thing I don't understand. How do the bonus tiles work? Do they have to be placed on the creeps' path? Or do they affect creeps regardless? Or maybe they only give that bonus to the tower placed on them? And if they do, does that tower have to kill the bug, or only hit it?
Other than the lack of this information in the help menu, it's quite easy to understand what to do in this game.

Kazeto: the tile bonuses apply to any tower placed on them. The shot speed bonus applies all the time but the score and cash bonuses only apply if that tower kills the bug. Generally for all bonuses you want your most upgraded towers on them, so they are getting the most kills. To indicate whether they are being applied when one of these bonuses is used it flashes its symbol in the border.


How I can get the "All that xxx" award?

John Blackburne June 24, 2011 11:05 AM

The 'All The xxx' awards are given out for finishing a level with only guns of a certain level, so e.g. 'All The Ones' means all your guns are upgraded to level one. This is checked when the level ends, so you can delete any guns that have not been upgraded (or have been upgraded too far). There also needs to be at least five guns.


Thank you for your quickly response.
Also, I found a bug that I can cheat the game.
If I take 3 bonuses and select the last one (bottom), the bonus are locked and I can fill all the bonus place with the bonus selected.
I send the image of the bug

Which version are you playing? There was a bug in version 1.1 which could have caused that but I fixed that bug and another with version 1.1.1, the version now on JayIsGames. Unfortunately I have little control over the versions that are out there on hundreds of sites, and no way of checking which version they have short of finding them on the sites and playing them. The version number is in the top right corner of the main screen.
