I've barely made it through campaign 1. About the 3rd mission or so of Campaign 2, I keep screwing up, forgetting to save when the battle starts and losing my squad. Between that and some really stupid luck in Campaign 1, I've restarted countless times.
(last time, someone hit my leader, from 4 or 5 hexes, whatever the max range is on a Tesla, and blew her head right off. This from a pilot I know to be at best Green. Argh. Time before that, lost like 90% of the titans on the battlefield to a fluke series of engine explosions, leaving the one surviving titan, the enemy, legless sitting in a woods hex on fire. Leastways I know that fight, despite what the game says, that game was a draw. Double argh.)
Gotten 2 of my squaddies up to rank 4 and into Medium Titans a few times.
Squad composition is nearly always the same. 4 jocks.
Leader CC, Cannon
Business Manager CC, Energy, Guided
Mechanic CC, Energy, Cannon or Unguided
Cyborg CC Energy/Cannon
Starting Titans/ Light titans
Swift Death becomes an Apparition or Driller(Light Titan, 2 Vibra Claws, 4 Lt Meson Guns)
Lightning (Pulse Laser, 2 GME's) (or, rarely now, a Pack Hunter) becomes a Raining Death (Lt Titan, 4 GMH's) or Ice Lord
Fireball becomes Inferno or Imp
OR
Banzai or Guru becoming an Imp
Pulseray (Stingray replacing all weapons with 2 pulse lasers) becomes Imp or Raygun (2 Pulse Lasers, 2 Heavy Meson Guns)
Medium Titans
Pariah (or whatever you call that Medium with all the GMH's)
Hipshot
Crucible
and that is about it.
As I said, I keep having to restart. I keep having memory lapses about every 6 - 8 battle I play through, and I forget to save the battle when I start. And of course, almost every time, that is the battle where every thing goes incredibly wrong. I mean, failing 98% rolls kind of wrong, while my enemy punches through green armor and damages my engine on 2 - 10% chances to hit wrong. I mean losing my head to 4 succesive GMH hits kind of wrong. It is kind of comical, in that, as long as I remember to save my game at the start of battle, I rarely will have to USE that save, things will rarely go wrong, luck will be about equal on both sides, and superior tactics (mine

) carries the day. I forget to save, and I don't care if I've got 4 mediums facing 4 recons, my entire squad dies horribly. (I actually had a Crucible go up against a Fireball in one such case, and lose. Was mortifying as hell. Was even worse when my Swift Death got base to base with a Pike, and got punched unconcious).
Not that I'm complaining, or blaming the game.
It is after all my fault for not saving. And, apparantly, my existence on this earth is solely for some god(s) amusement, as it is not like my luck in game is atypical of my luck in life.
Still, despite it all (maybe because of it all?) I AM enjoying the hell out of this game, despite sucking at it.
Now if you'll excuse me, I've finally gotten smart, and copied a squad over that is at c1m5, and I've got to try to run through it again.
