How to Play

Note: All keys can be redfined within the game to better suit your handset.

Movement

Use numeric keys or joystick to move.

Search

Use key 5 or center on joystick to stand still and search, pickup items and ascend/descend stairs.

Target/Look

Use key 0 to look around on the map/interact with things on the map or to target creatures if wielding a ranged weapon and ammo.

Use numeric keys or joystick to move cursor.

While in target mode use key 5 to select target or interact with things on the map.

Use key # to cycle between targets on the map

Combat

Move into monsters to attack them and into doors to open them.

Menu

Use * to bring up the game menu (inventory, character info, new game, save/load, message history, exit, version information)

Use # to go straight to the inventory screen.

Character stats

Your character has the four attributes; Attack, Defence, Magic and Speed. When displayed ingame the are shown as Attack/Defence/Magic/Speed.

Attack determines chance of doing damage in combat and the amount of damage that can be done in melee combat. Attack can be increased by using weapons and other items found in the dungeon.

Besides the attributes your character has Hit Points (Magic Points was removed in a recent version). When Hit Points reach 0 you die and have to start over.

Inventory

Available inventory slots are Melee Weapon, Missile Weapon, Armour, Shield, Helmet, Boots, Ring, Amulet. Use your inventory to equip/remove/drop/examine items you are carrying.

Handset requirements

Dweller is designed to run on any MIDP2 enabled handset. Older versions also work on MIDP1 handsets, but in 2009 MIDP1 support was abandoned.

ToDo list

  • Add a speed decrease when encumbered
  • Better monster AI
  • More varied dungeons
  • More items
