Since Clicker Heroes isn’t exactly a game that you actively play (at least not for more than a few minutes at a time), I’ve run through both of the Incursion Tower Defense games.
I’m not sure how I feel about them. I mean, I enjoy them, but they don’t bring anything new to the table. Yet despite not bringing anything new to the table, for the most part they are able to synthesize the pieces they borrow from into something that’s colorful and entertaining.
I’ll go right out and say “they’re no Kingdom Rush”, but the elements that are borrowed from Kingdom Rush are a big part of what makes them enjoyable.
It uses the common rock-paper-scissors mechanic that is similar to Cursed Treasure, with archers (light), soldiers (heavy), and mages (magic, duh), with light attacks being strong against magic armor, heavy attacks strong against light armor, and magic attacks strong against heavy armor. The most striking difference between Incursion and Cursed Treasure (towers only, no ‘units’) or Kingdom Frontier (towers and ‘units’) is that, like Demon Rift, towers ONLY create units. Unlike Demon Rift, however, towers can create mixed units (one tower can have an archer, a mage and a soldier, though there are disadvantages to that approach; archers & mages are terrible in melee until they reach high levels, so you want to keep them off the roads, usually too far away for any soldier grouped with them to auto-engage).
The difficulty of having your mages and archers being physical units rather than a tower is, like your soldiers, they can be killed. This is a particularly bad problem with the first game; since you couldn’t set target priorities, all units would attack the enemy farthers along the route, regardless of what was happening around or to the unit. Therefore, the most frustrating enemies were the archers, who would pick off your guys who were fighting against baddies further along the path, and Necromancers, who would continuously raise skeletons who gave you no money and would prevent you from ever getting to the Necromancer unless you mucked around with your deployment flags. Fortunately, this was fixed in the second game, which makes it a much easier and less frustrating experience.
The second game gives you a couple unique characters to play with, which also really helps in dealing with those obnoxious enemy archers and spellcasters. So much so that the fact that you can specifically target enemies with any of your troops doesn’t come into play nearly as much. The heroes (particularly when you’re given two) make things pretty dynamic.
The cool thing about the Incursion games is that each level has a unique thing going on, whether it’s an ally with a strange or difficult method of activation or an element of chaos, some monster who will kill everyone around it willy-nilly regardless of whether it’s your guy or a bad guy.
The look is similar to Kingdom Rush (one might go so far as to say a “borrowed aesthetic), which isn’t a bad thing. It plays similarly, though perhaps less frenetic. There’s kind of a strange difficulty curve in second game, where the middle few levels are extremely difficult, while the last few levels are fairly easy (last two levels I got perfects on the first try). The goblin chaingun IS gamebreaking and you WILL get a perfect against the final level if you stock up a couple of them. You might find yourself frustrated by how much slower you’re upgrading things (you are essentially having to upgrade 3 different towers per location), but it’s an understandable game balance issue. You’ll eventually figure out that a bare minimum of soldiers in the right places combined with as many ranged units as possible tends to work out best. At least in the second one. I might need to give the first one another go and test things. I feel like the first game had more waves of quick moving medium health regenerating monsters that had to be stopped, while the second one focused more on slow high HP high damage giants with a range of abilities. You needed lots of troops to slow down the former, while it was best to stay out of the latter’s way and just wizard zap and arrow them.
I won’t say that the Incursion games are my favorite TDs, but if you enjoyed either Kingdom Rush or Cursed Treasure, they’re worth checking out. You can play both for free on Kongregate.
