The two games fused into one: play as an Isaac character on the Plants vs. Zombies™: Replanted lawn, with all the Isaac content loaded from your own copy of The Binding of Isaac: Rebirth.
- Choose your character in the menus or before each level (Tab or the arrow keys): Isaac, Magdalene, Cain, Judas, or Eve, each with their own sprites, hearts, and stats.
- Fight alongside your plants: use ZQSD (WASD) to move, the arrow keys to shoot, and E to place a bomb.
- The lawn becomes an Isaac basement room, complete with walls.
- Zombies take the form of Isaac monsters: Gaper, Frowning Gaper, Mulligan, Pooter, Charger, Horf, Globin, Monstro.
- 33 items on pedestals (The Sad Onion, Polyphemus, Mutant Spider, Sacred Heart, Brother Bobby, Sister Maggy…), with their real effects and costumes for your character.
- Pickups dropped by monsters: coins (= sun for your plants), hearts, bombs, keys (one key = one item).
- An Isaac boss appears in the final wave (Monstro, The Duke of Flies, Gurdy, Chub), with a health bar, boss music, and an item reward.
- Isaac music in the menus, during gameplay, and during boss fights.
Single-player. You need both games on Steam. The first time you launch the mod, Isaac content is prepared once from your copy using the official ResourceExtractor tool included in Isaac's folder (about two minutes; you can start playing right away). No game files are included.
Credits: mashup by Kurition. MelonLoader (LavaGang, Apache-2.0) is included to load the mod, and NVorbis (Andrew Ward, MIT) is used to play Isaac music.
