I’ve been giving a lot of thought to the different game modes in Gratuitous Tank Battles. Here are my current thoughts:
Classic (Tower Defence) Mode
In this mode, you play a standard tower defence game. The enemies come at you in pre-scripted waves, and have to get across the map in sufficient numbers to win. When the final wave ends, the player has won. The player earns supplies for shooting down incoming units, and spends supplies by placing new turrets and troops in one of the many pre-defined squares along the multiple attack routes in real time.
Reverse (Tower Attack) Mode
This is the same, but swapped over, with you as attacker. The player earns a steady stream of supplies over time, and these supplies are spent on new units. The supply level is capped, so you can’t just sit there for ages and not place anything, as you waste potential troops in that way. The victory conditions are just like classic mode. This requires a fair bit of AI by the defender, who will intelligently (I hope) place defences along the routes that are most under attack, and select defending forces that balance out, and can best deal with what is being thrown at them.
Assault Mode (attack OR defence)
This is a mode that will also work online in challenges. The player, either as attacker or defender, has a fixed budget to build up an entire army in one go (or for attack, possibly in a number of separate waves). The army then tries to storm past all the turrets without any interaction by the player. The army can be uploaded as a challenge either by an attacker or defender.
Pitch Battle Mode
This is like GSB, but without any pathfinding :D Essentially the maps series of paths meet in the middle and big armies start at one end or the other, marching / driving towards each other and blasting away until one army is destroyed, or everyone is out of range of each other. The last (or biggest) army standing wins. This can also be done as an online challenge game. This is the only mode where both sides have moving units.
Of course, it’s impossible to really say which of these game modes will really work, and which will suck, A lot of it depends upon the exact implementation and numbers. I really think I should implement at least this list though, and give them all some decent testing before deciding if they work or not.
There is SO MUCH to do.
