IS THE GAMEPLAY MORE SHOOTING-BASED A LA TOMB 2, OR IS IT MORE PUZZLE-BASED, LIKE TOMBS 1 AND 3?
It's more puzzle-based, ala original Tomb Raider, but we're talking all-new puzzles, combined with Lara's new moves and the new inventory system. Items can be combined to help with puzzle solving and information retrieval as well as combat etc. Lara will have everything she needs to solve the puzzles within the near vicinity - so she won't have to spend ages running around the map to collect items. The difficulty will lie in actually working out the puzzles, rather than obtaining the items required to solve them - so it's certainly more like the original game in that respect.
We've got pressure-pads, timed levers, rotating hubs, wheels, hanging switches, switches in holes, levers and fulcrums, platforms and blocks that can be raised, trip wires, breakable walls, direction puzzles (using compass) to name but a few. The old levers from previous games are now obsolete! We have a whole range of new systems for Lara to operate, using a variety of new animations.
Of course we will have shooting but the targeting system has now been completely re-designed so Lara won't necessarily lock-on automatically but will be able to toggle between targets with her guns. In the previous games, as soon as Lara was near an enemy, she would lock-on - this really gave the game away and prevented her from locking onto any other enemy. We were unable to change this due to the fact that it was such a fundamental part of the engine.
Now that the heart of the engine has been ripped out and reconstructed, we can change the whole combat system and also introduce brand-new AI - enemies themselves will have a far greater range of ability and moves. They are given AI that enables them to follow Lara all over the map, mimicking and/or countering her moves - so it's no longer a case of being able to stand on a 'safe' ledge and shoot from a distance. Lara will really have to 'deal' with the majority of enemies so she won't be able to run away from them all - and if she does they'll soon be back to confront her again.
