Sample mod - Veteran Commander

The Mech Hangar's Commander walks out of the hangar at level 5, its last level: the jetpack is ready, and the 8 points the levels below it bring wait on its action ring for damage, health or defense. A Commander that falls comes back at level 5 rather than level 1.

The Commander still leaves the hangar only once its skill-tree node is bought (it asks level 40 and the hangar's level 3). Sample mod - All resources gives its profile level 99 and every skill point the tree can spend, so with both enabled everything the hangar does can be tried from the first wave.

It is one line of data: tower_data.json sets start_level in the hangar's hero. Any tower with a hero takes the key; see the modding guide. It is a gameplay mod, so it plays on the mod profile with achievements and leaderboards off.
