Invincible Escorter (10.4mb, ver 1.01, no install .zip) or iEscorter is a nice little Japanese shoot'em up with a twist. You do not control the main ship but the smaller escort ship that's attached to your main ship. Not only do you have to shoot the waves of enemies, but also need to block the incoming fire to protect your main ship. Your main ship is automatically controlled and while it does an ok job of avoiding incoming fire, it does make stupid mistakes and often, so you will need to watch not only enemies but your main ships movement as well. The game has 3 character ships, some good Bosses and different waves of enemies but only has auto fire. Not bad for a shooting game that took me a while to work out what was going on.
