I shall also salve my conscience by publicly confessing how I cheated - or made it easier for myself - so that others can
1. The Hired Guns Cheat versus Asteroids Cheat
Install the Hired Guns.OXP and go asteroid mining. When you have lock on an asteroid, fire your laser once at it. Eventually the hired guns will realise it is your target and go and shoot it for you. You are then credited with one kill. If you are lucky and it breaks into boulders, repeat the exercise. You will be credited with one kill for each boulder too. While you destroying asteroids does not give you kills, when wingmen do it, it does.
2. Using Hired Guns to Milk the Wasp Nest Cheat
Install the Wasps.OXP and go wasp hunting. Dock and launch from the Wasp Nest to make this even easier, you will have emerging wasps lined up with you so you can target them more easily. With your Hired Guns wingmen helping you, shoot the wasps around the wasp nest. One by one others will emerge, and they are easily killed. Eventually they seem to run out of wasps. That was when I edited the files for the Wasps.OXP to increase the number of defenders by a factor of ten. Once you've worked out the AI behaviour they are dead easy kills. Eventually, your wingmen will decide the nest itself is a target and set to work on destroying that too!
3. The Thargoid Invasion v Quirium Bomb Blast Cheat
Not really a cheat, perhaps, but not possible in vanilla Oolite. With the Galactic Navy OXP installed you can go on missions which include dealing with a major Thargoid invasion. Take a Quirium Bomb with you on these. When you get to the target system, make your presence known to the Navy, then head for the Thargoids as fast as you can, on your own. Drop a Quirium Bomb in the middle of their fleet. If they are far enough away and close enough together, sometimes you can take out the entire fleet with that one bomb - and get a bunch of easy kills in the process. If the Naval fleet also gets blown up by the secondary explosions you don't get any kills, but you don't become a criminal either.
4. The Kill the Dead Tharglets Cheat
This feels like a cheat to me. When the parent Thargoid has died and the baby Tharglets go off-line, you can scoop them for credits or shoot them for kills. Shooting a dead droid Tharglet is hardly the toughest assignment in town, but after a major Thargoid invasion there can be scores of these to be shot up through the system, for far more kills than can normally be accumulated in a short space of time. Obviously, you can't profit from this feature of Oolite if you've Quirium Bombed the Thargoid fleet to dust!
While the confessional is available, does anyone else have anything they wish to confess to?
