This game is a continuation, with some redesign, of my earlier game Geometric Invasion.
The Towers :
Gun - A big straight shooting cannon.
Mortar - Tosses bombs high into the sky causing large area explosions when they come back down.
Chiller - Slows down the escaping mobs.
Bolt - Sends out a bolt of electricity that never misses and sets mobs on fire.
Rocket - These rockets are relentless homing missiles with a big bang.
Laser - A laser beam goes forever and deals damage to anything in its path.
The towers have selectable targeting modes to help them hit the target you want.
Tower Targeting Modes :
Near - Target the closest mob.
Strong - Target the strongest mob.
Weak - Target the weakest mob.
Portal - Target the mob closest to the end of the line.
Fast - Target the fastest mob.
Slow - Target the slowest mob.
The Mobs :
There are 26 unique mobs and most of them have one ability or another; such as going faster at each turn, getting stronger or protection from certain towers.
A few of the mobs are Boss Mobs that enhance other nearby mobs by making them stronger, faster or healing them.
You can get a description of each mob in game, you curious little monkey!
You earn medals by beating maps, including the coveted Diamond Medal by beating any map on Pro skill level with all lives remaining. Everyone loves medals!
There are advertising banners, but only on the menu screens. These banners allow me to eat a pizza every couple of months and allow you to play a free game. Life is wonderful!
