Fun and unique game for 50 cents... normal price of $5 might be a bit steep considering some of the flaws.
The submap feature adds some depth (literally) to each mission, for example one mission the submap is an underground passage that brings you from outside the enemy's gates into the middle of the enemy's base. Unfortunately in some missions it feels a bit overused, sending you back and forth between maps with no apparent reason other than "it's there, so let's use it"; some of the submaps could have easily been implemented as a single map with some "natural" boundary like a mountain or river and a same-map teleport.
One of the campaign missions constantly crashes, which needs a substantial amount of patience (and liberal use of autosave) to eventually work through in order to continue the campaign progress.
Adding to the patience requirement is the speed of your units vs the size of the map vs the amount of back-and-forth required for some missions; basically, some of the game's mechanics result in artificially inflated playtime. One mission took me nearly 2 hours, simply because my hero unit had to walk from one end to the other of 3 different submaps, 2 to 4 times per map. While another mission has you waiting out the enemy's attacks--even if you've managed to gate off the spawn points with walls and guard towers--for what felt like an eternity (maybe it was only 20-30 minutes), before finally opening up a quest that lets you block the spawn points permanently. That quest itself then involves an extremely
slow unit, which you then have to direct to each of the furthest corners of the map before actually completing the mission.
There are a considerable number of glaring typos, which appear inconsistently, in various parts of the game. "Got to map" instead of "Go To", "Ho11y Place" instead of "Ho1y", "Train Scuto Rider" instead of "Scout", and others. And for some awful
reason, lowercase "L" is represented by the same character graphic as "1"; this can be seen as ear1y as the profi1e se1ect screen that appears before you can do anything e1se... where the defau1t profi1e name is "P1ayer".
These points aside, it's a pretty interesting theme for an RTS, with a fairly entertaining story; it was engaging enough that I stuck through the campaign to the end. Recommend this game only if it's on sale and only if you are resolved enough to suffer a few crashes.
